Astronomical time

The sky keeps
its own clock.

Sunlight, moonlight, eclipses and comet trails are all questions of time and place. No weather forecast—just the moments.

Sun and Moon times depend on where you stand.

Use your device location or choose a place manually. Coordinates are used only in this browser to calculate today’s sky times.

City-centre coordinates are accurate enough for everyday sunrise and sunset planning.
