About day length calculator
Day length is the time between sunrise and sunset. It changes across the year, and the change is bigger the further you are from the equator.
Seasons
In India the longest day is around the June solstice and the shortest around the December solstice. Northern cities see a larger difference than southern ones.
Compare cities
Check how many minutes of daylight are gained or lost each day, which is useful for planning outdoor work and travel.
A worked example
In northern India the day is a little over 10 hours long in December and nearly 14 hours in June. In the far south the change is smaller, from about 11 to 13 hours.
Why it matters
Day length affects farming, solar power output, travel plans and even mood in winter months. Use it to plan outdoor work and to estimate solar generation.
