Frequently Asked Questions
What is UTC time?
UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks and time. It's the successor to GMT (Greenwich Mean Time) and is used as the reference point for all time zones around the world.
How many time zones are there worldwide?
There are officially 24 time zones in the world, one for each hour in the day. However, some countries use time zones with 30 or 45-minute offsets, bringing the total number of unique time zones to about 39. Our world clock supports all of these variations.
How do I calculate time differences between countries?
Simply set a custom time using the time picker at the top of the page. All world clocks will automatically show you what time it will be in each location for your selected time.
When do Daylight Saving Time changes occur?
Daylight Saving Time (DST) changes vary by country and region. In the United States, DST begins on the second Sunday in March and ends on the first Sunday in November. In Europe, it begins on the last Sunday in March and ends on the last Sunday in October. Our world clock automatically adjusts for all DST changes.
