Timestamp Converter

Convert Unix timestamps to human-readable dates and back, in multiple formats.

Timestamp Converter translates Unix timestamps — the integer seconds or milliseconds since January 1, 1970 — into human-readable date strings in multiple formats, and converts date strings back into Unix timestamps. It supports both second-precision and millisecond-precision timestamps, handles the Now button for instant current-time reference, and outputs results in ISO 8601, UTC, local time, and a handful of other formats simultaneously so you can pick the one that fits your stack. Backend developers use it to decode timestamps in server logs, database records, and API responses. Frontend developers use it to figure out why a countdown timer is off by an hour. Mobile developers use it to debug timezone issues in date fields. Data engineers use it to convert timestamps between systems with different epoch representations. The tool runs entirely in your browser so you can paste timestamps from internal systems without any privacy concern.
