Calculate daylight hours, sunlight time, sunrise, sunset, usable daylight, outdoor work hours, daylight remaining, night hours, and seasonal daylight change. Use this daylight hours calculator for gardening, farming, hiking, camping, landscaping, photography, outdoor work, livestock checks, and nature planning.
Sunrise / sunset daylight hours:
The calculator estimates sunrise and sunset from date, latitude, longitude, and time zone, then calculates total daylight hours.
Manual sunrise / sunset:
Enter your own sunrise and sunset times to calculate daylight hours directly.
Daylight hours remaining:
Enter the current time to estimate how many daylight hours are left before sunset.
Seasonal daylight comparison:
Compare two dates to see how much daylight changes across the season.
A daylight hours calculator helps estimate how much sunlight is available for outdoor projects, travel, field work, gardening, hiking, and photography.
It can be useful for planning yard work, planting, harvesting, farm chores, camping, trails, outdoor events, landscape work, solar exposure, and seasonal schedule changes.
Your result shows total daylight hours, sunrise, sunset, usable daylight hours, daylight remaining, night hours, daylight percentage, task time comparison, cloud-adjusted useful daylight, and seasonal daylight change between two dates.
Subtract sunrise time from sunset time. For example, sunrise at 6:30 AM and sunset at 7:30 PM gives 13 daylight hours.
Usable daylight hours are the daylight hours left after subtracting any buffer you want after sunrise and before sunset.
Daylight changes because Earth is tilted on its axis, causing longer days in summer and shorter days in winter for many locations.
No. Daylight saving time changes the clock time of sunrise and sunset, but the total amount of daylight stays the same.
