Time Zone Converter
Choose a date, time and source time zone to see what time it is everywhere else, with daylight saving time applied.
How it works
Conversions use the browser's built-in IANA time zone database, so daylight saving rules are applied for the chosen date. The input is interpreted as wall-clock time in the selected zone and converted to the corresponding instant, which is then displayed in every other zone.
Tip: for recurring international meetings, check the dates around the March and October clock changes, since the US and Europe switch on different weekends.
Frequently asked questions
Why are some zones a half hour off?
Several regions such as India (UTC+5:30) and parts of Australia use half-hour or 45-minute offsets.
What is UTC?
Coordinated Universal Time, the reference time standard. It has no daylight saving.
Are the offsets exact for past or future dates?
Yes for dates where the zone rules are known to your browser's time zone database. Governments can change the rules.
