Common timezone questions
How do I compare time across different time zones?
Add the cities or IANA time zones you want to compare. The timeline shows each location’s matching local hour side by side, including date changes like +1 or -1 day.
How can I find a good meeting time across time zones?
Add every participant’s city, then scan for hours where the work-hour bands overlap. Pick a row where all or most locations are inside normal working hours.
How do I know if a coworker is currently in working hours?
Add your coworker’s city and check the current-time marker against the work-hour band. You can adjust the work range if their team uses different hours.
How do I convert a city’s time to my local time?
Add your city as the first reference column and add the target city. Select or read the target city’s hour in the timeline to see the matching local hour in your column.
Does the converter handle daylight saving time?
Yes. The tool uses IANA time zones through the browser’s time zone data, so DST-aware cities are converted using the correct offset for the selected date.
Can I share a timezone comparison with others?
Yes. Use Share setup to copy a link with the selected cities and time so others can open the same comparison.
