What Is the World Clock?
The world clock (with seconds) shows the current time in selected cities around the world: perfect for planning international meetings, arranging travel, or simply respecting someone's remote schedule.
You can customize the list of cities displayed to match your environment and needs.
How Do I Use the World Clock?
The clock shows your system time by default. Click any city in the list to switch to the time in that location. You can also click the full-screen icon top right to see the time in full-screen mode (only works on desktop).

Is daylight saving time considered?
Yes, the clock automatically adjusts for daylight saving time (DST). When cities change their clocks seasonally, the displayed times update automatically.
How Many Time Zones Are There?
In theory, there should be 24 standard time zones worldwide, each one hour apart. But since some regions use 30-minute or 45-minute offsets (India at UTC+5:30, Nepal at UTC+5:45), there are actually 38 different clock times in the world at any given moment.
Behind the scenes, computer programs and operating systems use a database of many more time zone identifiers to handle adjustments for daylight saving and different regions.
