Frequently Asked Questions

Each clock is synchronized with your device and adjusted to the target city's official time zone using the IANA time zone database. As long as your device clock is set correctly, the displayed time is accurate to the second.

Yes. We use the IANA time zone database, which includes the daylight saving time rules for every region. When a city switches between standard time and summer time, its clock updates automatically without any action from you.

Open any city page and use the time difference tool to compare it with another location. It shows the exact number of hours ahead or behind, taking each city's current time zone and DST status into account.

Use the search bar at the top of the page to enter the city name and then press the Search button. This will open that city's page with the current clock, time zone details, and weather forecast.

We cover thousands of cities worldwide, but very small towns may not yet be listed. In that case, try searching for the nearest larger city in the same time zone, which will show the same local time.

UTC (Coordinated Universal Time) is the global time standard. A UTC offset, such as UTC+1 or UTC-5, tells you how many hours a city's local time is ahead of or behind UTC. This offset can change during the year in regions that observe daylight saving time.

You can learn more in our guide: What Is UTC and Why Is It Important?
