Time zone converter

What time is it there?

Working across time zones is part of everyday life: scheduling a call with a colleague overseas, joining a webinar announced in someone else's time, following a live event or a sports fixture, phoning family abroad or booking a flight whose times are given in the local time of each airport. A wrong conversion means a missed meeting. This tool converts a specific date and time between any of the places on the list.

Why it is harder than adding hours

The difference between two places is not always the same. Many countries move their clocks forward in summer and back in winter, and they do so on different dates, so the gap between New York and London, usually five hours, is four for a couple of weeks in spring and again in autumn. Some zones differ by half hours or by 45 minutes. The tool works from the internationally maintained time zone database used by your browser, so it applies the rules that were in force on the date you choose, and daylight saving is handled automatically.

What each result shows

• The time in the chosen place, in the format of your language.
• The weekday and date, which can be different from the place you started in.
• The offset from UTC at that moment, for example UTC-04:00, which reveals whether daylight saving is in force.
• A note when the local date is the next or the previous day, a common trap in scheduling.

Using it to schedule

Enter the proposed time in your zone and convert to the zones of the other people. If a proposal is in the middle of the night for someone, try another time. For finding a time that suits several places at once, use the meeting time finder, which shows all the hours side by side.

What it does not do

It lists major cities rather than every time zone in the world, and it relies on your browser's time zone data, so very recent changes to a country's rules might not yet be reflected on an old device. For critical events, such as a flight or a legal deadline, confirm the local time with the organiser.
