How many time zones exist?

There are 24 main time zones, each offset by one hour from UTC. Some regions use half-hour or quarter-hour offsets.

UTC (Coordinated Universal Time) is the international standard. GMT (Greenwich Mean Time) is the timezone at 0 offset.

What is daylight saving time?

Daylight saving shifts clocks forward/backward seasonally. This converter accounts for DST automatically.

How do I plan calls across time zones?

Use this converter to find convenient meeting times for participants in different time zones.

Do all countries use time zones?

Almost all countries use time zones. Some use non-standard offsets (half-hour, quarter-hour differences).

What's the difference between time zone and UTC offset?

Time zones are regions with the same UTC offset. UTC offset is the difference from UTC/GMT.
