How to convert a Unix timestamp
- Paste timestamps or dates into Input, one per line. Type now for the current time.
- Numbers become dates, shown in your chosen zone, as ISO 8601 in UTC and as a relative time (“3 years ago”). Dates such as 2026-07-04 18:30 become timestamps.
- Choose whether dates are shown and read in your time zone or in UTC.
