Time-based Evolution

Time-based Evolution refers to Pokémon that evolve during a certain time of the day. This method of Evolution was introduced in Generation II.

==In the core series games==
With the introduction of time in Generation II, time-based Evolutions were also introduced. The table below summarizes the in-game times during which Pokémon that evolve based on time can evolve in various games across the generations.

 evolves into from 5:00 p.m. to 5:59 p.m. (17:00 - 17:59) only (opposite the real time in Pokémon Ultra Moon).
===Generation II===
 was given two new Evolutions to take advantage of the changing time: , which it would become if its friendship maxed out during the morning or day, and , which it would become if its friendship maxed during the night.
===Generation III===
====Pokémon Ruby, Sapphire, and Emerald====
In , the time-based Evolutions are available even though there are no visible day and night periods in the overworld.
====Pokémon FireRed and LeafGreen====
In , however, the time function is completely absent, allowing it to be more like the Generation I games. This also makes it impossible for Eevee to evolve into either Espeon or Umbreon in these games. In order to do so, the player would have to trade Eevee to , or and have it evolve in one of those games.
===Generation IV===
In Generation IV, many new Pokémon Evolutions are influenced by the time of day; for example, will only evolve into at night.
===Generation VII===
====Pokémon Let's Go, Pikachu! and Let's Go, Eevee!====
In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, which is set in perpetual daytime, evolves regardless of the time of day.
===Generation VIII===
====Pokémon Sword and Shield====
In , prior to becoming , the time of day outside of the Wild Area is determined by the player's current point in the story, not the system time. This affects both the lighting of the environment and time-based Evolutions. However, even before becoming Champion, the time of day in the Wild Area is exclusively determined by the system time.
====Pokémon Legends: Arceus====
In , the moon phase now play a significant role, unlike in previous installments where they were purely cosmetic. can only evolve into by using a Peat Block during a full moon. A full moon is also required to activate the event for Request 67: The Clefairy's Moonlit Dance. There are eight different moon phases, and the moon phase changes every two nights.
==In the side series games==
===Pokémon Colosseum===
In , is unable to evolve into either or due to the absence of the time feature. However, the player character Wes starts the game with both Espeon and Umbreon. 
===Pokémon XD: Gale of Darkness===
In , due to the absence of the time feature, Eevee can only evolve into Espeon or Umbreon via the Sun Shard or Moon Shard, respectively, a method that is not time-dependent.
==In the spin-off games==
===Pokémon GO===
In Pokémon GO, there are several time-based Evolutions. Daytime in GO approximately corresponds to the time between sunrise and sunset in the player's location; nighttime corresponds to the time between sunset and sunrise. To evolve , there must be an in-game , which typically corresponds to when there is a real-world full moon. Most have two evolution options (for either or ), though certain rarer Rockruff have one evolution option for . Dusk Form Lycanroc must be evolved around sunset in the player's location.
As of July 9, 2024, the Adventure Effect of allows any daytime evolutions to evolve at any time, while the Adventure Effect of allows any nighttime evolution (including Ursaring, regardless of a full moon). Both Adventure Effects allow Rockruff to evolve into Dusk Form Lycanroc at any time.
