Complete Guide: Time Zone Converter
Everything you need to know about using this tool effectively
The Time Zone Converter transforms a time from one time zone to another. You select a source city or time zone and a target city or time zone, enter the time, and the tool calculates the equivalent. It uses the browser's built-in time zone database, which includes all IANA time zones with daylight saving time rules. All processing happens in the browser.
This tool uses JavaScript's Intl.DateTimeFormat and Date objects to convert between IANA time zones. It accounts for daylight saving time transitions automatically. You can select from a list of major cities or type a time zone abbreviation.

UTC offsets range from -12 to +14.
Some time zones have half-hour or quarter-hour offsets (e.g., India is UTC+5:30).
When scheduling meetings, aim for times that fall within business hours for all participants.
Does it handle daylight saving time?
Yes. The tool uses the browser's IANA time zone database, which includes all DST transition rules. The converted time accounts for DST in both the source and target zones.
What time zones are available?
All IANA time zones are available, covering every country and region. You can select by city name or time zone abbreviation.
Is my data sent to a server?
No. All conversion happens in your browser using JavaScript. Nothing is transmitted.
Can I see the current time in other zones?
Yes. The tool displays the current time in the selected time zones alongside the conversion.
How do half-hour time zones work?
Some regions use half-hour offsets from UTC. India is UTC+5:30, Newfoundland is UTC-3:30. The tool handles these correctly.
