Unix Time to Date
Convert a Unix timestamp into human-readable UTC and local date/time. Supports both seconds and milliseconds.
Auto-detect treats larger values like 13-digit timestamps as milliseconds.
| Metric | Value |

Privacy: conversions run locally in your browser. No timestamps are stored or transmitted.
How it works
The converter interprets the timestamp as either seconds or milliseconds since the Unix epoch (1970-01-01 00:00:00 UTC), then formats the result as both UTC time and your browser's local time.
Examples
- 0 → 1970-01-01 00:00:00 UTC
- 1735689600 seconds → a readable UTC and local date
- 1735689600000 milliseconds → same point in time expressed in ms
