About this tool
Converts a date and time from one time zone to up to five others using the browser’s IANA time zone database, accounting for daylight saving automatically. It also shows the UTC offset at that moment.
How to use it
- Enter the date and time and choose the source zone.
- Add the zones you want to compare.
- Read each converted time with its offset.
Frequently asked questions
Does it handle daylight saving?
Yes. The offset is calculated for the specific date, not a fixed value, so summer and winter times are correct.
What about a meeting that crosses a DST change?
Convert each candidate date separately; a one-hour shift can move a meeting outside business hours.
