Estimate daylight hours, sunrise, sunset, solar noon, night length, and daylight remaining for a selected date and location. Enter latitude, longitude, time zone, and date to calculate day length and useful daylight details.
Date:
Select the day you want to estimate daylight hours for.
Location:
Enter latitude and longitude. Positive latitude is north, negative latitude is south. Positive longitude is east, negative longitude is west.
Time zone:
Select the UTC offset for the location and add daylight saving time if local clocks are currently observing DST.
Daylight result:
The calculator estimates sunrise, sunset, solar noon, total daylight hours, night length, and remaining daylight.
A daylight hours calculator is useful for weather planning, gardening, outdoor work, hiking, camping, photography, travel, solar planning, farming, fishing, and estimating how much usable daylight is left in the day.
This calculator uses a simplified solar estimate. Official times may vary slightly due to elevation, atmospheric refraction, terrain, and the local horizon.
Your result shows the amount of daylight between sunrise and sunset for the selected date and location. It also shows night length, solar noon, daylight remaining from the entered current time, and whether the selected time is during daylight.
Daylight hours are calculated by estimating sunrise and sunset for the date and location, then subtracting sunrise time from sunset time.
Daylight changes because Earth is tilted as it orbits the sun. The effect is stronger farther from the equator.
No. Daylight saving time changes the clock time of sunrise and sunset, but it does not change the actual length of daylight.
Daylight hours are most extreme near the poles, where some dates can have very long daylight or very long darkness.
