Frequently Asked Questions

A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. There are 24 main time zones offset from UTC (Coordinated Universal Time) by whole or half hours. Some zones like India (UTC+5:30) and Nepal (UTC+5:45) use non-standard offsets.

Daylight Saving Time is the practice of advancing clocks by 1 hour in summer to extend evening daylight. Not all countries observe DST — most of Asia, Africa, and parts of South America do not. The US and EU observe DST, but transition on different dates, causing the offset between them to change briefly each year.

UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks and time. It does not observe DST and serves as the reference from which all other time zones are calculated. UTC replaced GMT (Greenwich Mean Time) as the world standard, though the two are practically equivalent for everyday use.

IANA (Internet Assigned Numbers Authority) time zone identifiers use the format Region/City (e.g., America/New_York, Asia/Tokyo). These are the standard used by operating systems, programming languages, and this tool. They automatically account for DST transitions, historical changes, and political boundary shifts.
