What time is sunrise today?
Sunrise time depends on the date, your latitude and longitude, and your local time zone. Locations farther north or south see larger seasonal changes, while locations near the equator have more consistent sunrise and sunset times throughout the year.
How sunrise and sunset are calculated
This calculator uses an astronomical formula based on solar declination, the equation of time, latitude and longitude. It calculates the sun's position for the selected date, then converts the result into the time zone you choose.
Day length variation by season
Day length changes through the year because the Earth is tilted on its axis. In London, June days last more than 16 hours, while December days are closer to 8 hours. The effect becomes stronger the farther you are from the equator.
