About this clock
How accurate is the clock on this page?
The clock ticks from your device's own clock, so it is only as accurate as that clock. When the page loads it compares your device time with our server's clock and tells you if yours is off by more than a fraction of a second. Phones and computers that sync over the network are usually within a few hundredths of a second.
How does the page know my time zone?
Your browser reports its IANA time zone (for example Europe/Berlin or America/Chicago) from your device settings. Nothing about your location is sent to us; sunrise and sunset are shown for the largest city we list in the same time zone.
What is the difference between my local time and UTC?
UTC (Coordinated Universal Time) is the reference clock every time zone is defined against. Your local time is UTC plus or minus your zone's offset, which changes twice a year if your zone observes daylight saving time.
