This translates a date and time from one time zone into the equivalent moment in another, accounting for each zone's offset from UTC. It covers a set of major cities and regions, making it useful for scheduling anything involving people in different parts of the world.
How to use it
- Select the date and time you want to convert.
- Choose the source time zone the entered time refers to.
- Choose the target time zone you want it converted into.
- Read the converted date and time.
- Adjust any field and watch the result update instantly.
When it helps
- Scheduling a call with colleagues or clients in a different time zone.
- Figuring out what time a live event starts in your own local time.
- Coordinating a flight's departure and arrival time across zones.
- Converting a deadline given in one time zone into your own.
- Checking what time it currently is somewhere else for a quick call.
Good to know
- Daylight saving can shift a zone's offset for part of the year, so double check results around a transition date.
- Confirm which time zone a meeting invite was originally given in before converting, since a wrong assumption there produces a confidently wrong answer.
- When scheduling across a lot of time zones, using UTC as a neutral reference in writing helps avoid confusion.
- For a recurring meeting across time zones, double check the converted time again close to the meeting date if it falls near a daylight saving change in either zone.
- If you're unsure whether a specific place currently observes daylight saving, check before an important conversion, since not every region does, even within the same country.
Questions
Does this account for daylight saving automatically?
Yes, it uses each zone's actual offset for the date you enter, which accounts for daylight saving where it applies, rather than a fixed year round offset.
Why do some countries use unusual offsets, like a half hour?
A handful of places, like India and parts of Australia, use a 30 or 45 minute offset based on historical and geographic decisions rather than any mathematical need.
Can I convert between two zones, neither of which is mine?
Yes, both the source and target can be set to any supported option, regardless of where you actually are.
Why does a meeting shift by an hour depending on the time of year?
This usually happens because one or both zones observe daylight saving, which shifts their offset from UTC for part of the year and back again.
Can I convert for a date far in the future?
Yes, though be aware daylight saving rules can occasionally change by government decision, so a far future conversion relies on the rules currently in effect.
Do all time zones shift by whole hours?
No, a few use a half hour or 45 minute offset from neighboring zones, which is worth double checking if a conversion result looks unusual.
