Frequently Asked Questions

Yes. Times come from your browser's built-in timezone database, which tracks each region's DST rules — so London correctly shows GMT in January and BST in July without you doing anything.

Add each participant's city, then enter your proposed time in the converter. Seeing 9:00 AM New York render as 11:00 PM Tokyo tells you immediately to keep looking — aim for overlap inside everyone's working hours.

It's how far a zone is from Coordinated Universal Time — New York is UTC-5 in winter, Tokyo is UTC+9. Offsets make mental math between zones easy: the difference between the two offsets is the hour gap.

They tick every second based on your device's clock. If your computer's time is synced (which modern systems do automatically), the displayed times are accurate.
