Sky

Sky is an in-game phenomenon that mimics a Trainer's real-world sky experience and the astronomical events related to it. The current sky is reflected in the Map View and capture phase according to the Trainer's location. The sky mechanic defines the daytime, nighttime and dusk according to Trainer's real-world sunset and sunrise times, which are elements used both for evolving and spawning certain Pokémon.

Periods of the day
Daytime is the period of the day during which the Trainer's location experiences natural illumination from direct sunlight, between the sunrise and the sunset. Nighttime is the opposite period of Daytime, between the sunset and sunrise. The in-game Dusk is defined as one hour before the sunset until one hour after the sunset. The weather image and some weather icons reflect the period of the day.

Periods of the year
A Season is an in-game phenomenon that mimics the real world seasons rotating through winter, spring, summer and autumn every three months, bringing major changes to Pokémon spawn, egg hatchlings, and raid bosses. Some, in-game events are themed based on the Season they occur in.

The Equinox is the day of the year in which the daytime and nighttime have the same duration occuring twice each year, around the end of march and september. The Solstice is the day in either hemisphere that has either the most sunlight of the year (summer solstice) or the least sunlight of the year (winter solstice). These phenomena are related to several in-game events such as Equinox and Summer Solstice. Solrock and Lunatone swap regions during solstice.

Time-based spawns
Some Pokémon can only spawn during particular time of day or year outside of events.

Time-based Evolution
Some Pokémon can only evolve during particular time of day.

Sky elements
A real-time sky mechanic that mimics Trainers sky light based on their geographical location is available since July 2021.

Niantic considers to be full moon very close to real world full moon, unless a special event happens:


 * Jan, 2023 1 p.m. to 8 p.m. (UTC+14:00) Lunar New Year 2023
