Find local sunrise, sunset, and daylight length for any latitude, longitude, and date using solar geometry in your browser.
Sunrise, sunset, and daylight length
Enter latitude, longitude, a calendar date, and your local UTC offset to estimate sunrise, solar noon, sunset, and total daylight. Calculations use standard solar geometry with atmospheric refraction adjustment for the solar disk.

Frequently Asked Questions
How accurate are these times?
Results are suitable for planning and education. Horizon height, elevation, and local terrain can shift observed sunrise and sunset by a few minutes.
What UTC offset should I use?
Use the offset for your civil time zone on the selected date, including daylight saving if it applies (for example -4 for US Eastern Daylight Time).
Why do I see polar day or polar night?
At high latitudes the sun may stay above or below the horizon all day on certain dates. The tool reports that condition instead of clock times.
Does this account for refraction?
Yes. A standard 0.833 degree correction is applied so times align with when the upper edge of the sun crosses the horizon.
