Understanding Time Zones
Time zones are regions of Earth that observe uniform standard time for legal, commercial, and social purposes. The world is divided into 24 time zones based on UTC (Coordinated Universal Time), also known as GMT (Greenwich Mean Time). Daylight Saving Time (DST) is observed in many countries to make better use of daylight hours during warmer months.

What is the time difference between New York and London?
The time difference between New York and London is typically 5 hours, with London being ahead. However, this can vary by 1 hour during DST transitions since the US and UK change clocks on different dates.
What time is it in Tokyo, Japan?
Tokyo uses Japan Standard Time (JST), which is UTC+9. Japan does not observe daylight saving time, so Tokyo maintains the same UTC offset year-round.
How do time zones work?
Time zones are regions that observe the same standard time. The world is divided into 24 time zones, each roughly 15 degrees of longitude wide. UTC (Coordinated Universal Time) is the primary time standard.
What is Daylight Saving Time (DST)?
Daylight Saving Time (DST) is the practice of advancing clocks by one hour during warmer months so that darkness falls at a later clock time. Not all countries observe DST.
