Time Zone Converter
Enter a date and time in one time zone to instantly see the equivalent time in another — perfect for scheduling calls and meetings across countries.
How to use the Time Zone Converter
Select a date and time, choose the time zone that time is in ("From"), then choose the time zone you want to convert it to ("To"). Click "Convert" to instantly see the equivalent local time, including the date if it shifts to the day before or after.
Why use a time zone converter?
Scheduling a call with a client overseas, coordinating a remote team across countries, or just figuring out what time a live stream starts in your local time can be confusing with manual time zone math — especially with daylight saving time changes. This tool handles the conversion accurately using your browser's built-in time zone data.
Frequently asked questions
Does this account for daylight saving time?
Yes. The converter uses your browser's built-in time zone database, which automatically applies daylight saving time rules for the specific date you select, not just a fixed offset.
Can I convert between more than two time zones at once?
Currently the tool converts between one "From" and one "To" time zone at a time. To check multiple zones, repeat the conversion by changing the "To" selection.
Is my data stored anywhere?
No. This tool is part of the Toolyard collection of free, browser-based utilities. All calculations run locally in your browser using standard time zone data — nothing you enter is uploaded to a server or stored anywhere.
Why time zone math is deceptively hard
Beyond the basic offset between two zones, daylight saving time complicates things further — not every country observes it, and the ones that do don't all switch on the same dates, so the gap between two time zones can actually change by an hour depending on the time of year. Manually tracking which region is currently in daylight saving time is a common source of scheduling errors for international teams and remote workers.
Scheduling across time zones without the guesswork
A meeting time that's convenient at 9am in one city might land at 11pm somewhere else — and "roughly figuring it out" is exactly how international meetings end up scheduled at inconvenient or unintended times. Converting precisely, rather than approximating, avoids both the awkwardness of a badly timed call and the confusion of a missed one.
Common uses
Remote teams scheduling meetings across offices in different countries, travelers adjusting to a new time zone or planning calls back home, and event organizers coordinating a webinar or livestream for an international audience all rely on accurate time zone conversion rather than mental estimation.
