Time

Time is a mechanic in the Pokémon games. It was introduced in Generation II and has been a major component of almost all games released afterward. Time affects both the evolution of several Pokémon and whether certain Pokémon can be found in the wild. Some events may take place at a specific time of day, or on a particular day of the week. Pokémon Legends: Arceus and Pokémon Scarlet and Violet use their own in-game time system and don't depend on the player or console's real time.

Berries are governed by the time function, maturing after a certain amount of time has passed. Much like weather, the games' time function has been revised and expanded in each subsequent generation after its introduction.

In the core series games

Generation II

In Generation II, the changing time of day is one of the games' distinctive features. Wild encounters vary based on the time of day; several Pokémon were designed with this in mind, such as Hoothoot and Noctowl.

At the beginning of all three games, the player is required to set the clock, even before selecting a name. The default time is 10:00 AM (10:00). When the player speaks to their Mom at the start of the game, the player must specify whether it is currently daylight saving time or not; they can adjust the clock for entering or exiting daylight savings time.

The clock can be reset through a code in all three games, although it is more difficult to do so in Pokémon Crystal. For the Virtual Console versions, adjusting the time on the Nintendo 3DS clock does not affect the in-game time.

Times of day

Morning	Day	Night
4:00 AM–9:59 AM (04:00–09:59)	10:00 AM–5:59 PM (10:00–17:59)	6:00 PM–3:59 AM (18:00–03:59)

Morning

Morning, referred to as Morn in-game, is the time from 4:00 AM to 9:59 AM (04:00–09:59). Many Pokémon Trainers are still asleep and there are many Bug-type Pokémon in the wild. However, the wild Pokémon that appear in the Morning are mostly the same as Day, with only slight differences. During the Morning, the rising sun tints the entire landscape with a yellowish hue.

Day

Day is the time from 10:00 AM to 5:59 PM (10:00–17:59). The landscape is not tinted at all during this time, making it seem closer to the Generation I games (which do not have a time system). Day is the busiest time, as most people are up and about at this time and a wide variety of Pokémon appear.

Night

Night, referred to as Nite in-game, is the time from 6:00 PM to 3:59 AM (18:00–03:59). Wild Pokémon battles taking place at night use a slightly different music track. The world is colored a bluish-purple, and buildings have their lights on. If interacted with, the Pokémon Center lady will note that the player is still active despite the time, before healing the party.

Days of the week

Main article: Days of the week

When the Pokégear is first received, the player's mother will ask them to set the day of the week as well. This affects several things, such as the National Park's Bug-Catching Contest and which of the Week Siblings appears, though not much else.

Resetting the clock

In the Western and Korean versions, a secret function for resetting the game's clock that requires a password may be accessed from the title screen. The password is generated from the player's name, Trainer ID number, and current amount of money (Blackshark's GSC Clock Password Generator). The game will then reboot and the main menu will return the "TIME NOT SET" error message. Proceeding will then load a screen in which the player can adjust the clock's data, including the weekday. Due to being based on the Japanese version, the password only takes into account the first five characters of the player's name.

While the function for manually resetting the clock is not available in the Japanese versions, the main menu error and the actual clock adjustment screen exist in all versions as they are used for when the clock data is invalid or corrupted.

Generation III

Unlike Generation II, Generation III had no separate time periods, or even an ability to check the time in-game unless the player traveled back to Littleroot Town, where they had set an analog clock at the beginning of the game. The overworld lighting does not change during different times of the day. Also, unlike Generation II, the time-based events were very few and extremely far between, with the clock mostly running to keep track of the growth of planted Berries (although this was not completely foolproof). Additionally, there was no way to change the clock in this generation, not even for daylight saving time.

There were, however, some time-based functions in the games. For example, Shoal Cave's water level would change every six hours, at 3:00 and 9:00 AM and PM (03:00, 09:00, 15:00, 21:00). Just the same, the time-based Evolutions are available.

Although a small part of the game, some events occur on a daily basis. Some NPCs give the player one Berry every day. Lilycove Department Store gives out Pokémon Loto Tickets for the Pokémon Lottery Corner, with the winning number changing daily. An old man who lives in Pacifidlog Town looks out for Mirage Island, and will, every day, generate a random number between 0 and 65535 and if this number matches the personality value of any of the Pokémon in the party, Mirage Island will appear in the game.

Time was only used in the Hoenn-based games. Time-based evolutions cannot trigger in Pokémon FireRed and LeafGreen. In Pokémon Colosseum, the player receives Espeon and Umbreon, the only two Pokémon at the time that were result of time-based evolution, at the beginning of the game. In Pokémon XD, the player's Eevee can evolve into Espeon or Umbreon with the Sun Shard or the Moon Shard in the Bag, respectively.

Times of day

Day	Night
12:00 PM–11:59 PM (12:00–23:59)	12:00 AM–11:59 AM (0:00–11:59)

Generation IV

In Generation IV, the time function returned fully with many features from Generation II, including changes in the overworld lighting and in the availability of wild Pokémon at different times of day, being Nocturnal, Matutinal, or Diurnal. However, this time it uses the Nintendo DS's system clock. The three time periods from Generation II return, with smoother transitions between them.

A calendar and day of the week system are also present. The game keeps track of the date of capture of every Pokémon. Some in-game events are influenced by the day of the week; for example, Drifloon only appear in the Valley Windworks on Fridays, and battles with Barry in the Battle Zone can only be initiated on weekends.

The Pokédex also has a new function that displays where Pokémon are found in each time period. When it is first opened, the Sinnoh Pokédex will also default to the current time of day.

Additionally, in Pokémon HeartGold and SoulSilver only, the generic battle transitions change during nighttime (except for wild Pokémon in water). Cave battles are always treated as if it was nighttime, but places with cavelike encounters such as Sprout Tower or Ilex Forest properly account for the time.

Times of day

Morning	Day	Night
4:00 AM–9:59 AM (04:00–9:59)	10:00 AM–7:59 PM (10:00–19:59)	8:00 PM–3:59 AM (20:00–03:59)

Morning

Morning tints everything a pale blue color, changing from dark blue of night into bright blue of daytime. Morning lasts from 4:00 AM to 9:59 AM (04:00–9:59).

Day

Everything takes on its natural color during the day. Day lasts from 10:00 AM to 7:59 PM (10:00–19:59), with twilight lasting from around 5:00 PM (17:00) until night sets in. Twilight has its own set of eyecatches.

Night

Much like its Generation II counterpart, the world is dark, but pockmarked by the bright lights of buildings. Night lasts from 8:00 PM to 3:59 AM (20:00–03:59), with lights in buildings turning off at 12:00 AM (00:00). A majority of areas in Sinnoh have slightly different music during the night, including Pokémon Centers, though this is not true in Kanto and Johto.

Generation V

In Pokémon Black and White, the concept of seasons was introduced. These are akin to the seasons in the real world, only to allow for less restrictive gameplay, the seasons change with every month.

Time of day now varies depending on the current season. As in HeartGold and SoulSilver, day is divided in four different parts: morning, when floodlights in the cities switch off and the sun starts to rise; daytime, when everything is lightened; evening, when the floodlights switch on in the cities and everything starts to be lit with an orange hue; and then nighttime, which is characterized by a darker landscape, both in the overworld map and in battle.

In favor of seasons, Pokémon are no longer found at different times of day, meaning Pokémon that can be found in the current season can be found anytime during the season.

Time of day in relation to season

Season	Morning	Day	Evening	Night
Spring	5:00 AM–9:59 AM (05:00–09:59)	10:00 AM–4:59 PM (10:00–16:59)	5:00 PM–7:59 PM (17:00–19:59)	8:00 PM–4:59 AM (20:00–04:59)
Summer	4:00 AM–8:59 AM (04:00–08:59)	9:00 AM–6:59 PM (09:00–18:59)	7:00 PM–8:59 PM (19:00–20:59)	9:00 PM–3:59 AM (21:00–03:59)
Autumn	6:00 AM–9:59 AM (06:00–09:59)	10:00 AM–5:59 PM (10:00–17:59)	6:00 PM–7:59 PM (18:00–19:59)	8:00 PM–5:59 AM (20:00–05:59)
Winter	7:00 AM–10:59 AM (07:00–10:59)	11:00 AM–4:59 PM (11:00–16:59)	5:00 PM–6:59 PM (17:00–18:59)	7:00 PM–6:59 AM (19:00–06:59)

Generation VI

Time continued to be based on the system clock in Generation VI, now using the 3DS's clock to track time. Seasons from Generation V did not carry over, however. Therefore, the intervals for when morning, day, evening, and night occur are now constant. Unlike in previous generations, where the time period transitions lasted a few seconds, they may last up to 15 minutes, allowing less abrupt changes in the overworld lighting. If the 3DS clock is changed, time-based events will not occur for 24 hours and any Berries will reset.

In Pokémon Omega Ruby and Alpha Sapphire, the game always starts at daytime, the 3DS's clock being taken into account only after the player interacts with the analog clock in their room.

Times of day

Morning	Day	Evening	Night
4:00 AM–10:59 AM (04:00–10:59)	11:00 AM–5:59 PM (11:00–17:59)	6:00 PM–8:59 PM (18:00–20:59)	9:00 PM–3:59 AM (21:00–03:59)

Generation VII

Pokémon Sun, Moon, Ultra Sun and Ultra Moon

In Pokémon Sun and Ultra Sun, the clock functions conventionally, matching the Nintendo 3DS's clock; however, in Pokémon Moon and Ultra Moon, the game runs its time offset by 12 hours from the 3DS's clock. In Pokémon Moon and Ultra Moon, this difference mainly affects the day-night cycle. Events that refresh daily still refresh when the 3DS's clock hits midnight (or noon in-game in Moon and Ultra Moon) and events that rely on the day of the week correlate to the day according to the 3DS's clock.

Specific scenes in the game, such as in the beginning of the game, will be set at specific times, with the clock effectively frozen until that part of the story is completed. Regardless of the games, the player is eventually able to travel to a world that has the opposite time by using the Ultra Wormhole at the Altar of the Sunne/Moone.

Different Pokémon can once again be found depending on the time of day. In the Rotom Pokédex, these species are denoted with a different icon when viewed in the Habitat menu. Certain areas in Alola have slightly different background music depending on the time of day, such as Hau'oli City.

Times of day

Note that these times refer to the time on the 3DS's clock. That is, within Pokémon Moon and Ultra Moon, "day" still starts at 6 AM (06:00) as far as the game world is concerned. This may be seen at any place that acknowledges the time, such as the Pokémon Center Café.

Game		Morning	Day	Evening	Night
Sun	Ultra Sun	6:00 AM–9:59 AM (06:00–09:59)	10:00 AM–4:59 PM (10:00–16:59)	5:00 PM–5:59 PM (17:00–17:59)	6:00 PM–5:59 AM (18:00–05:59)
Moon	Ultra Moon	6:00 PM–9:59 PM (18:00–21:59)	10:00 PM–4:59 AM (22:00–04:59)	5:00 AM–5:59 AM (05:00–05:59)	6:00 AM–5:59 PM (06:00–17:59)

Pokémon Let's Go, Pikachu! and Let's Go, Eevee!

Despite Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! having a few time-based features, they are set in perpetual daytime, much like the original Pokémon Yellow.

Generation VIII

Pokémon Sword and Shield

In Pokémon Sword and Shield, time is set to specific times of day during the main story as a narrative device. This affects all areas of Galar outside of the Wild Area, and even influences evolution. However, daily events (such as the Battle Café matches) still reset at midnight according to the system time. After the player becomes Champion, time is no longer pre-set outside the Wild Area, and functions solely based on the system time, even during post-game story scenes like the arc involving Sordward and Shielbert.

Times of day

Morning	Day	Evening	Night
6:00 AM–9:59 AM (06:00–09:59)	10:00 AM–6:59 PM (10:00–18:59)	7:00 PM–7:59 PM (19:00–19:59)	8:00 PM–5:59 AM (20:00–05:59)

Pokémon Brilliant Diamond and Shining Pearl

In Pokémon Brilliant Diamond and Shining Pearl, the time function remains the same as Generation IV's, including changes in the overworld lighting and in the availability of wild Pokémon at different times of day, being Nocturnal, Matutinal, or Diurnal. However, this time it uses the Nintendo Switch's system clock.

A calendar and day of the week system are also present. The game keeps track of the date of capture of every Pokémon. Some in-game events are influenced by the day of the week; for example, Drifloon only appear in the Valley Windworks on Fridays, and battles with Barry in the Battle Zone can only be initiated on weekends.

Times of day

Morning	Day	Night
4:00 AM–9:59 AM (04:00–9:59)	10:00 AM–7:59 PM (10:00–19:59)	8:00 PM–3:59 AM (20:00–03:59)

Morning

Everything is bright and sunny, with the lighting facing from the west. Morning times are from 4:00 AM to 9:59 AM (04:00–9:59).

Day

Everything takes on its natural color during the day. Day lasts from 10:00 AM to 7:59 PM (10:00–19:59), with twilight lasting from around 5:00 PM (17:00) until night sets in. Twilight has its own set of eyecatches.

Night

Much like its Generation IV counterpart, the world is dark, but pockmarked by the bright lights of buildings. Night lasts from 8:00 PM to 3:59 AM (20:00–03:59), with lights in buildings turning off at 12:00 AM (00:00). A majority of areas in Sinnoh have slightly different music during the night, including Pokémon Centers.

Pokémon Legends: Arceus

Pokémon Legends: Arceus has its own time system, independent from the system clock. A minute in real life corresponds to an hour in-game. The player can instantly change the current time of day, and even skip to the next day, by resting at their quarters or the bed present at each Base camp.

Times of day

Morning	Day	Evening	Night
4:00 AM–10:59 AM (04:00–10:59) 7 real minutes	11:00 AM–4:59 PM (11:00–16:59) 6 real minutes	5:00 PM–7:59 PM (17:00–19:59) 3 real minutes	8:00 PM–3:59 AM (20:00–03:59) 8 real minutes

Changing time

The time can be changed by going to a Base camp or the player's bed in Jubilife Village and choosing to rest until a certain time. Selecting "Just a little while" will heal the player's party members, but not advance the current time. Selecting the remaining options will advance the day/night cycle to the following times:

Until morning	Until midday	Until evening	Until nightfall
6:00 AM (06:00)	11:00 AM (11:00)	6:00 PM (18:00)	8:00 PM (20:00)

Resting in this manner will however reset the current state in the area and despawn any time-specific Pokémon encounters, as well as resetting timings for space-time distortions and other similar timed events.

Generation IX

Pokémon Scarlet and Violet

Pokémon Scarlet and Violet have their own time system, which with 1 real-life day equal to 20 in-game days. This time can be influenced by the player by altering the system clock prior to opening the game,^[1] with the time value being determined when the game is first opened.^[2] However, the day/night cycle does not begin until the player loads into the overworld, so any changes to the system clock while the game is loading or at the in-game start menu have no effect, the game will load the time from when the game was initially opened. The day/night cycle lasts 72 real minutes in total, repeating 20 times over the course of 24 hours. Different Pokémon can spawn depending on the time of the day; unlike previous games, however, the brief period of evening has its own separate spawns defined as well.

Opening the map by pressing Y will show an icon in the top-center of the map^[3] indicating the time of day. This icon will dynamically update to show the current time period, however Morning does not have its own unique icon, instead sharing an icon with Day.^[4] While the player is in Area Zero, this is the only way to tell the time of day without having to come out.

There are two exceptions to the day/night cycle, the first being that during the tutorial, the time will be locked to Day until visiting Naranja Academy^S/Uva Academy^V for the first time and obtaining Koraidon^S/Miraidon^V.

Area Zero is also unaffected by the day/night cycle (with Flutter Mane being the only exception due to a quirk^[5]), with time-exclusive species and forms spawning regardless of the current time in the rest of Paldea.

The current time is shared between all players in the same instance while playing in co-op via Union Circle, determined by the player hosting the group.

Due to their physical locations being relatively distant from Paldea, both Kitakami and the Terarium experience different timezones, with Kitakami being 18 (real life) minutes ahead of Paldea, and the Terarium being 18 (real life) minutes behind Paldea.

If defeated, static encounters such as the treasures of ruin, and fixed symbol encounters such as wild Tera Pokémon will reappear if the player reboots their game after one hour has passed in the Switch's internal clock following their defeat. This is independent from Scarlet and Violet's in-game time system.

Time-specific events

This section relates only to events that occur at specific times but not necessarily on a particular day. For events that occur only on specific days of the week (but not at a particular time), see days of the week.

Time-based Evolutions

Main article: Time-based Evolution

Several Pokémon evolve during a certain time of day.

Generation II

• The Clefairy event in Mt. Moon Square will trigger between Monday night at 8:00 PM and Tuesday morning at 4:00 AM (20:00–4:00).
• Daisy will massage the player's Pokémon between 3:00 and 4:00 PM (15:00–16:00).
• Officers will only challenge the player at night from 6:00 PM to 3:59 AM (18:00–03:59).
• The wild battle theme played in Johto and some locations in Kanto is slightly different at night from 6:00 PM to 3:59 AM (18:00–03:59).

Effects of changing the clock

If the clock is reset, every time-based event moves forward and can be repeated right away. Time-based events with a specific window need the clock to be set within that frame. In these games, the time-based events are:

• The Clefairy event.
• The Haircut brothers.
• The Lapras special encounter.
• The Lucky Number Show.
• Picking Apricorns and Berries from trees.
• Receiving Apricorn Balls from Kurt.
• The S.S. Aqua voyage.
• The rematch against Silver at Indigo Plateau.
• The Trainer House battle.

Generation III

Pokémon Ruby, Sapphire, and Emerald

• The tides in Shoal Cave depend on the time of day. It is high tide from 9:00 AM to 3:00 PM (09:00–15:00) and 9:00 PM to 3:00 AM (21:00–03:00), and low tide from 3:00 PM to 9:00 PM (15:00–21:00) and 3:00 AM to 9:00 AM (03:00–09:00).

There is no side-effect to changing the clock in these games.

Generation IV

Pokémon Diamond, Pearl, and Platinum

This section is incomplete. Please feel free to edit this section to add missing information and complete it. Reason: What music? Many effects of changing the clock are missing

• Joggers will only challenge the player in the morning from 4:00 to 9:59 AM (04:00–09:59).
• Policemen will only challenge the player at night from 8:00 PM to 3:59 AM (20:00–03:59).
• The player can catch Rotom once from 8:00 PM to 3:59 AM (20:00–03:59) in the Old Chateau.
• The Pal Park transfer can occur only once every 24 hours.
• Certain music changes depending on if it is daytime or night.

Effects of changing the clock

• Pal Park: the player must wait 24 hours from when the game is opened after changing the clock to be able to migrate. If the clock was changed, the game to needs sync with the new time so that the penalization period starts running. This can be accomplished by booting the game and saving. Otherwise, the penalization period cannot begin nor end. If the game was booted in a different system, the penalization period can be prevented simply by not saving and, if available, returning the game to the system it's synchronized with.

Pokémon HeartGold and SoulSilver

• The Clefairy event in Mt. Moon Square will trigger between Monday night at 8:00 PM and Tuesday morning at 4:00 AM (20:00–4:00).
• Daisy will massage the player's Pokémon between 3:00 PM and 4:00 PM (15:00–16:00).
• Policemen will only challenge the player at night from 8:00 PM to 3:59 AM (20:00–03:59).

Effects of changing the clock

If the game detects a different clock, either by changing the date or time of the system or by booting the game in a different system and saving, time-based events will be affected differently.

The following time-based events can be done by directly changing the clock to the time window in which they're active:

• The Bug-Catching Contest.
• The Clefairy event.
• Commemorative pictures.
• Items available in the Athlete Shop at the Pokéathlon Dome.
• The Lapras special encounter in Union Cave.
• Pokégear radio shows.
• Obtaining the Gym Leaders' phone numbers.
• Rematch calls with the Gym Leaders.
• The rematch against Silver at Indigo Plateau.
• The S.S. Aqua voyage (including receiving an item from the captain).
• The shops in the Goldenrod Tunnel.
• The Week Siblings appearing.

The following daily events can be done by changing the clock to 23:59 and letting the clock roll over to the next day in-game:

• Buena's Password in Goldenrod City. The password will not be available right after the clock rolls over. Saving the game on the new day, then changing the clock for a second time to when (or waiting until) her show is on air (2:00, 5:00, 8:00, 11:00, 14:00, 17:00, 20:00, and 23:00) is necessary.
• Daisy's massage in Pallet Town. The massage will not be available right after the clock rolls over. Saving the game after midnight, then changing the clock for a second time to when (or waiting until) the massage can be requested (15:00–16:00) is necessary.
• Mass outbreaks.
• Hearing a new trendy phrase from the old man on Route 16.
• Picking Apricorns from trees.
• The Pokémon Lottery Corner in Goldenrod City.
• Receiving Apricorn Balls from Kurt.
• Receiving Seals in Olivine City.
• The Trainer House battle in Viridian City.
• Receiving a Ribbon from one of the Week Siblings.

The following time-based events are impacted negatively if the game detects any time change:

• Berry growth: instead of calculating how long it has been since the game was last saved and matching the Berry's timer to the system's clock, the Berry's timer resumes right from when the game was last saved.
• Safari Zone area upgrades: the invisible day counter will freeze for 24 hours, period after which it will resume counting days from where it left off when the game was last saved. Just like with Pal Park in Pokémon Diamond, Pearl, and Platinum, if the clock was changed, the game to needs sync with the new time so that the penalization period starts running. This can be accomplished by booting the game and saving. Otherwise, the penalization period cannot begin nor end. If the game was booted in a different system, the penalization period can be prevented simply by not saving and, if available, returning the game to the system it's synchronized with.

Generation V

• Trainers may be battled every day in the Big Stadium and Small Court. However, they cannot be battled during sports events that occur during certain times and days of the week.
• The Royal Unova can be boarded only during the evening.
• The player can purchase Casteliacones once per day. In Black and White, this is only possible on Tuesdays and outside of winter.
• A businessman in Lacunosa Town gives out a Pecha, Leppa, Lum, or Bluk Berry on Sundays^BW/every day^B2W2 during nighttime.
• The Black Empoleon biker gang will "take over" the Tubeline Bridge on Friday evenings and nights, and their leader can be challenged.^BW
• Morimoto and Nishino^B2W2 can be battled in Castelia City once per day. In Black and White, the player must have entered the Hall of Fame for this to be possible.
• A girl on Route 8 will give out one of the four weather duration-extending items per day. The rock changes depending on the time of day:

Time of Day	Rock given
Morning	Damp Rock
Day	Heat Rock
Evening	Smooth Rock
Night	Icy Rock

In the spin-off games

Pokémon Mystery Dungeon series

In the Pokémon Mystery Dungeon series a day has passed every time the player comes back from an adventure or plays Sentry Duty. During the story, one day can incorporate clearing several dungeons in a row with save points in between.

Clearing Blizzard Island gives the player the choice to go through Crevice Cave or not, if the player chooses not to a day has passed. When going to Hidden Land, a day never passes unless the player leaves back to Treasure Town or completes Temporal Tower.

Pokémon Conquest

In Pokémon Conquest, The shortest unit of time measured in Pokémon Conquest is a month (not real time). Every story starts on January, Year 1. In two stories (The Rebel and Tragic Determination), the goal is to defeat Nobunaga before January, Year 4 (before 3 years had passed).

Opposing armies will only attack at the very start of the month, except for one time in The Legend of Ransei where Shingen or Kenshin attack after they decline a battle with the player.

Pokémon GO

In Pokémon GO, day and night changes depend on sunset and sunrise in the player's location. The difference between day and night is the appearance, the music, and the evolution of some Pokémon. Additionally, Raid Battles do not spawn during a specific range of hours at night. Sunny weather during the day becomes Clear weather during the night; the effects of the two, however, are identical.

If a Mystery Box is acquired and opened, three days must pass before it can be opened again.

For the time-based Evolutions, see Time-based Evolution → Pokémon GO.

These times are all set based on the player's current time zone. The daily events (such as sleeping time, shop events, etc) last from 4:00 AM to 3:59 AM the next day. The week starts on Monday.
