FAQ
Q: What is UTC?
A: UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. It is essentially the same as GMT (Greenwich Mean Time) and does not change with daylight saving time.
Q: What is DST?
A: Daylight Saving Time (DST) is the practice of advancing clocks by one hour during warmer months to extend evening daylight. Not all countries observe DST — many tropical and equatorial regions do not.
Q: How many time zones are there?
A: There are 24 standard time zones based on 15° longitude intervals, but many countries use half-hour or quarter-hour offsets, resulting in 38+ distinct UTC offsets in practice.
