About the Time Zone Converter
The timezone converter converts any time between any two world timezones, accounting for daylight saving time.
How to use the Time Zone Converter
How time zones work
Every zone is defined as an offset from Coordinated Universal Time (UTC) — London sits near UTC, New York is several hours behind, Tokyo several ahead. Crossing the International Date Line can also shift the calendar day, which is why a call can land “tomorrow” for the person at the other end.
Daylight saving time
Many countries move their clocks forward in spring and back in autumn, but not on the same dates, and not at all in some places. That makes manual time-zone maths error-prone around the changeover. The converter applies the correct daylight saving rules for each location so the result stays right.

Daylight saving time
Most of Europe and North America adjust clocks twice a year. The UK switches in late March (forward) and late October (back). The US follows a slightly different schedule. Countries near the equator typically don't observe DST.
Conversions use your device’s official IANA time-zone database, which includes current daylight-saving rules, so results stay accurate across DST changes. Built and maintained by TooLegend. Last reviewed June 2026.
