Date Format Converter
Enter a UTC date and time to see the same instant as an ISO string, UTC-readable text, local-readable text, and Unix timestamps.
Enter a date and time to see ISO, UTC, local, and Unix formats.
How it works
The ISO string is the standard UTC representation (ending in Z). UTC and local readable strings use the Intl API with full date and time styles. Local output follows your browser's time zone.
Unix timestamps are shown in seconds and milliseconds since 1970-01-01 UTC. For timestamp ↔ date conversion in both directions, use the Unix Timestamp Converter.
