Frequently Asked Questions
Does it account for Daylight Saving Time?
Yes. Offsets are computed at the specific moment you enter, so DST transitions are handled correctly for all IANA timezone identifiers.
Why does my local time differ from the "from" zone result?
The tool interprets the date and time you enter as belonging to the selected "from" timezone, not your browser's local timezone. Choose your local zone in the dropdown to match your system clock.
What timezone identifiers are used?
This tool uses IANA timezone database names (e.g. America/New_York, Europe/London), the same standard used by operating systems and programming languages worldwide.
