Sunrise Sunset Calculator
Estimate sunrise, sunset, solar noon, day length, and twilight times from a date, latitude, longitude, and UTC offset.
Enter a planning date, latitude, longitude, and the location's UTC offset for that date. The calculator estimates sunrise, sunset, solar noon, and day length locally in your browser without sending location data anywhere.
Use the local calendar date for the place you are checking.
Use the offset active on that date, such as -5 for EST, -4 for EDT, 0 for UTC, or 5.5 for IST.
Positive values are north of the equator; negative values are south.
Positive values are east of Greenwich; negative values are west.
Choose which horizon angle to use for the primary rise and set times.
How it works
The calculator uses the selected date, latitude, longitude, and UTC offset to estimate when the Sun reaches the chosen horizon angle. Official sunrise and sunset use the common apparent-horizon convention that accounts for the Sun's disc and typical atmospheric refraction.
Results are best for planning, photography, gardening, travel, and rough daylight checks. Local terrain, buildings, elevation, unusual refraction, weather, and polar conditions can shift what you actually see at a specific spot.
The UTC offset is entered by you because time zone and daylight-saving rules depend on location and date. Use the offset that applies at the place on the selected date, then review the UTC times and calculation breakdown if you need to verify the result.
