World clocks display the current time across different time zones. The Earth is divided into 24 main time zones, each roughly 15 degrees of longitude apart. As the Earth rotates, different parts of the world experience daylight at different times.
Our world clock system synchronizes with atomic clock servers using Network Time Protocol (NTP) to maintain accuracy within milliseconds. This ensures you always see the precise current time for any location.
The clock automatically adjusts for Daylight Saving Time (DST) changes in applicable regions. DST dates vary by country and region, but our system keeps track of these changes to display the correct time year-round.
