When to use it
The time zone converter shows what a particular date and time will be in other cities around the world. Use it to schedule an international meeting or call, plan a webinar or live stream for viewers in several countries, catch a flight connection, or check the right moment to message family abroad without waking them.
How to convert a time
- Enter the Date and Time you want to convert.
- In Time zone, choose where that time applies, such as New York. Press Now to use the current moment.
- The list shows the same moment in every city on your list, with its UTC offset, the date there, the time difference, and a label: working hours, evening/morning or night.
- To add a place, type it in Add a city or time zone (for example Tokyo, Dubai or Los Angeles) and press Add. Remove a city with its ✕ button.
A worked example
You’re in New York and want to hold a video call at 9:00 AM on Wednesday 18 November 2026 with colleagues in London, Kolkata, Tokyo and Sydney. Enter that date and time with New York as the time zone. The converter shows London at 2:00 PM (working hours), Kolkata at 7:30 PM, Tokyo at 11:00 PM and Sydney at 1:00 AM on Thursday (night). Moving the call to 5:00 PM New York time gives Sydney 9:00 AM, but makes it 3:30 AM in Kolkata, so you may need two sessions.
Tips for scheduling across time zones
- Always include the time zone in invitations, such as “9:00 AM New York (2:00 PM London)”.
- Watch the date line. Asia and Australia are often already on the next day.
- Check dates near March and October–November, when clocks change in many countries.
- Use UTC for schedules involving many regions; it never changes for daylight saving.
- Rotate awkward slots in recurring meetings so the same team isn’t always up late.
Common mistakes
- Assuming a fixed difference all year, which breaks around daylight saving changes.
- Using abbreviations like CST or IST, which can mean different zones (IST is used for India, Ireland and Israel). Use city names instead.
- Forgetting half-hour zones such as India (UTC+5:30) and parts of Australia.
- Converting from the wrong starting zone. Check the Time zone field before sharing a time.
