How to convert a local time between two IANA time zones

1. Enter the date-time

   "Date-time" accepts ISO-style strings (`2026-05-21T14:30`) or with a zone (`2026-05-21T14:30Z`). The tool treats unannotated strings as being in the FROM zone.

2. From / to zones

   "From zone" and "To zone" take IANA identifiers like `America/New_York`, `Europe/Berlin`, `Asia/Tokyo`. UTC offsets (`+05:30`) work too. DST is handled — the same wall-clock time in March vs November can shift differently.

3. Press Run

   Result returns `iso` (the converted instant in ISO 8601 with offset) and `formatted` (a human-readable version in the target zone). Both reflect the same moment; only the presentation differs.

4. DST edge cases

   Spring-forward and fall-back days can produce two valid "local 1:30 AM" times (or none, depending on direction). The tool picks the standard interpretation, but if you're scheduling around a transition, double-check with a real timezone library.
