Frequently Asked Questions

What is UTC?

Coordinated Universal Time — the primary time standard by which the world regulates clocks. It replaced GMT as the reference.

Does this handle daylight saving time?

This uses fixed UTC offsets. During DST, select the appropriate offset (e.g., EDT is UTC-4, not EST UTC-5).

How many time zones are there?

There are 24 standard time zones, but with half-hour and quarter-hour offsets, there are over 38 practical time zones.
