Convert an ISO 8601 instant
Use Z for UTC or include an explicit offset such as2026-01-15T09:30:00-05:00. An offset makes the input an unambiguous instant that can be displayed reliably in UTC, local time, or another timezone.
Offset and timezone are different
An offset such as −05:00 describes one relationship to UTC. An IANA identifier such as America/New_York carries historical and future daylight-saving rules. Store the IANA zone as well when a future event must remain tied to a location’s wall-clock time.
Avoid ambiguous date strings
Formats like 04/05/2026 mean different things in different locales. For data and APIs, prefer ISO 8601 with an explicit offset; this converter intentionally rejects browser-specific free-form parsing.
