Major phase times
Which time zone does this calendar use?
Each major phase happens at the same instant worldwide. The cards show that instant in KST (UTC+9) and UTC; your local calendar date may be different. This month’s events are grouped by their KST date.
Daily phase and illumination are sampled at noon KST (03:00 UTC). Moonrise and moonset are for Seoul, not your current location. For local rise and set times, choose your location in Moonrise and moonset tonight.
