Time Difference: New York to Frankfurt

Summary

See the live time in New York and Frankfurt side by side, with the exact hour offset and a meeting-time overlap finder.

How it works

1. Your browser's built-in Intl.DateTimeFormat API retrieves the current wall-clock time for each city's IANA time zone.
2. New York uses the "America/New_York" zone (UTC-5 in winter / UTC-4 in summer).
3. Frankfurt uses the "Europe/Berlin" zone (UTC+1 in winter / UTC+2 in summer) — Frankfurt and Berlin share the same legal time zone.
4. The tool computes the hour offset by comparing the UTC offsets of both zones at the current moment.
5. Both clocks tick every second so the displayed times are always accurate.
6. A color-coded badge highlights the offset, including during DST transition weeks when it can briefly differ from the usual 6 hours.
