Pokémon Sleep: New Moon Day (June 2026)

The New Moon Day event is back for June 2026 in Pokémon Sleep. This is the fourteenth New Moon Day event, and the sixth of 2026! This event is held once a month for a total of three days—on the day of the new moon and the days before and after it. This event will have special appearance rates and it will be harder for Pokémon to become full.

Every time you encounter a Pokémon with a special appearance rate during your New Moon Day sleep research, its friendship points will increase by 3 even if you don’t give it Poké Biscuits.
