Time Zone Converter
Meeting at 3pm — but whose 3pm? Convert any date and time between time zones in one click, daylight saving included.
How to use
- Enter the date and time. Type the moment as it reads in the source time zone — a meeting invite, a flight departure, a stream start.
- Choose both zones. "From" is where that time is; "to" is where you are (or where you're converting to). Common zones sit at the top of each list, with every world zone below.
- Convert. The converted time appears instantly, with the zone abbreviation and the hour difference between the two zones. Use Swap to flip the direction.
Frequently asked questions
Does the time zone converter handle daylight saving time?
Yes — conversions use your browser's built-in time zone database, which knows every daylight saving rule past and future. Converting a July date between New York and London gives a 5-hour difference; the same date in January gives 5 hours too, but New York to Sydney shifts between 15 and 16 hours depending on the season. You never have to think about DST yourself.
How do I schedule a meeting across time zones?
Enter your proposed meeting time in your own zone as the "from" zone, then convert to each attendee's zone. Pick a slot that's humane for everyone — the converter shows the hour gap, which makes it easy to spot a 9am–5pm overlap. Pro tip: convert the final time back into your own words in the invite ("3pm CT / 1pm PT") so nobody has to do math.
What do time zone abbreviations like EST, EDT, and BST mean?
They're short names for a zone at a specific time of year: EST is Eastern Standard Time (UTC−5, winter), EDT is Eastern Daylight Time (UTC−4, summer). The converter shows the correct abbreviation for the date you entered, which is exactly why abbreviations alone are unreliable for scheduling — always pin a date to a full zone name instead.
Why is the converted time off by an hour sometimes?
Almost always daylight saving: the two zones changed their clocks on different dates, so the gap between them is different for part of the year. The US and Europe, for example, switch on different weekends in March and October, creating a few weeks where the usual difference shifts by an hour. This converter accounts for all of that automatically.
