How to Use the Time Zone Converter

Select a time and a reference city or time zone, then add the other cities you want to compare — the tool shows the equivalent local time in each one simultaneously, automatically accounting for each region's current daylight saving status on the selected date.

The Time Zone Converter compares multiple locations at once — here's how to set it up for a specific meeting or call.

Setting a reference time and date

Choose the specific date, not just a time — since daylight saving transitions can shift the correct offset between zones, using the actual date of the event being planned (rather than today's date, if scheduling for a future date) ensures the conversion is accurate for when it will actually happen.

Adding and comparing multiple cities

Add each relevant city or time zone to see all the converted times side by side — useful for finding a time that works across every participant's zone at once, rather than converting one pair of zones at a time manually.

Frequently asked questions

Does the tool handle daylight saving automatically?

Yes — the conversion is calculated for the specific date selected, accounting for each region's daylight saving rules and transition dates rather than using a fixed, potentially outdated offset.

Can I compare more than two time zones at once?

Yes — adding as many cities as needed shows all their equivalent local times together, which is useful for scheduling a call across more than two locations.
