About the Date Time Converter
ISO 8601, Unix timestamps, RFC 2822, human-readable local time - every API, database, and log format seems to pick a different one. Converting between them by hand is trivial to get wrong, especially across timezones and daylight-saving boundaries.
Paste a date in any common format and get every other representation at once: Unix seconds and milliseconds, ISO 8601 with and without offset, UTC, and your local time. Everything converts in your browser.
How to use
- Paste a date, timestamp, or ISO string.
- All formats update instantly - Unix, ISO 8601, UTC, local.
- Check the timezone interpretation carefully (Z, +00:00, or naive).
- Copy the format your target system expects.
Frequently Asked Questions
What does the Z at the end of a timestamp mean? ▾
Z means UTC - zero offset from coordinated universal time ("Zulu"). 2024-02-26T13:06:54Z and 2024-02-26T13:06:54+00:00 are the same instant expressed two ways.
Why do Unix timestamps come in two lengths? ▾
Seconds since 1970 is the classic format (10 digits); many systems, including JavaScript dates, use milliseconds (13 digits). Mixing them up shifts a date by about 53,000 years, which is a common bug.
