Sunrise & Sunset Calculator

Computes sunrise, sunset, solar noon, day length and civil twilight for any latitude, longitude and date using the NOAA solar position algorithm, accurate to about a minute. Can use your device location with one click.

Notes

  • Above the polar circles the sun may not rise or set at all on some dates; the tool reports polar day and polar night explicitly.
  • Times are shown in your browser's time zone; for a place in a different zone, convert them with the time zone converter.
  • Everything runs locally in your browser; nothing you enter is sent to any server.
