Frequently Asked Questions About Solar Times

Learn how sunrise and twilight angles are computed worldwide.

We calculate sunrise and sunset based on the exact minute the top edge of the sun crosses the horizon, using the trusted solar position models developed by NOAA. We also factor in atmospheric refraction—the way Earth's air gently bends light rays—so your times reflect what you actually see in the sky.
