Daylight Hours Calculator
For gardening, solar planning and photography: get the exact length of day, sunrise and sunset, and how the day compares with the longest and shortest days of the year.
Pick a date and location to calculate daylight.
How to use
- Pick the date and enter latitude and longitude, or choose a preset city.
- Set the UTC offset (Pakistan is UTC+5 all year).
- Read the daylight length, sunrise, sunset, and the comparison with the solstices.
Uses the standard NOAA solar calculation, the same math as the sunrise and sunset tool. Day length is measured between sunrise and sunset at the official zenith of 90.833 degrees and excludes twilight; civil twilight adds roughly 25 to 35 minutes of usable light at each end in Pakistan latitudes.
