How this tool works

The selected wall-clock time is resolved in the source IANA time zone, then the same instant is formatted in the destination zone using that date's daylight-saving rules.

Assumptions

The entered wall-clock time belongs to the selected source IANA zone. Conversion preserves the instant and applies the browser's installed time-zone rules for that date.

Limits to know

Time-zone rules can change by government action. Spring-forward times may not exist and fall-back times may occur twice; choose the intended occurrence and confirm consequential appointments.
