Timezone Converter
Timezone Converter translates a date and time from one time zone into another, using the full IANA time-zone database so daylight saving is handled correctly for every zone and date.
Pick the source and target zones, enter a time, and see the converted result with each zone's UTC offset and the difference between them. It all runs in your browser.
How to use Timezone Converter
- 1
Choose the zones
Select the source zone the time is in and the target zone to convert to.
- 2
Enter the date and time
Type the wall-clock time in the source zone — it defaults to now in your zone.
- 3
Read the conversion
See the equivalent time in the target zone, each UTC offset, and the hour difference.
Daylight saving, handled for you
Time-zone offsets are not fixed: many regions shift by an hour for part of the year, and the rules differ by country and change over time. Because this converter uses the browser's IANA time-zone data, it applies the correct offset for the exact date you enter, so a summer meeting and a winter meeting convert correctly even between the same two cities.
The UTC offset shown next to each zone reflects that specific date, not a generic average.
Planning across zones
Scheduling a call across regions is the classic use case: enter the proposed time in your zone and read it in a colleague's. The difference line tells you at a glance how many hours apart the two zones are on that date.
To express a converted moment as an epoch value, pair this with the Timestamp Converter.
Frequently asked questions
- Does it account for daylight saving time?
- Yes. Conversions use the IANA time-zone database, so the correct offset is applied for the specific date you enter.
- Which time zones are supported?
- Every zone your browser knows about — typically the full IANA list of several hundred zones — with a curated fallback on older browsers.
- Is my data sent anywhere?
- No. Conversions run entirely in your browser.
