About SunHours

SunHours is a minimal website for checking sunrise and sunset times. Every city has a fast, simple page that’s easy to read on mobile and desktop.

On SunHours you can

• See today’s sunrise and sunset times for a city
• Check the length of daylight
• See a live countdown to the next sunrise or sunset
• Jump quickly between cities using search

How SunHours calculates times

• Sunrise/sunset is calculated from each city’s latitude and longitude
• Times are shown in the city’s local time zone and adjusted for daylight saving time
• Pages are regenerated daily, so results stay fresh

SunHours aims to be accurate and reliable, but no warranty is given. Data and calculations may be affected by time zone updates, location precision, and edge cases (for example, polar regions). Use at your own risk.
