Time Zone Converter

About Time zone converter

Converts a date and time from one time zone into several others, and draws an hourly meeting planner that highlights when everyone is inside working hours. It relies on the IANA time zone data built into your browser, so daylight saving rules are applied for the date you choose.

How to use it

1. Pick a Source time zone; the page starts on your device's zone.
2. Choose a Date and Time, or press Now to load the current moment.
3. Use Add a time zone to search for more places, and press Remove on any row you do not need.
4. Adjust Working hours start and Working hours end in the Meeting planner and look for cells outlined as working for every zone. Copy comparison saves the list as text.

When to use it

• Scheduling a stand-up between teammates in different regions.
• Checking what time a live stream or product launch starts locally.
• Finding the shared working hours of three offices before proposing a call.
• Confirming an offset such as UTC+05:30 before entering it into a calendar.

Questions about Time zone converter

What happens if I choose a time that does not exist?

During a spring-forward gap the time moves ahead. Entering 02:30 on 8 March 2026 in New York gives 03:30, the first valid moment after the clock jump.

And when a time occurs twice in autumn?

The first occurrence, still on daylight saving time, is used. That is the earlier of the two identical clock readings.

What do the +1d and -1d marks mean?

They show that the hour falls on the day after or before your reference day, so you can spot a call landing at midnight elsewhere.

What if no hour works for every zone?

The planner says so. New York, London and Dubai on a summer weekday, for example, have no hour inside 9 to 17 everywhere, though New York and London share three.

Do you store the zones or times I pick?

No. Everything is calculated in your browser with its built-in Intl support and nothing is sent to a server.
