// HOW IT WORKS
A Unix timestamp counts the seconds since 1970-01-01 00:00 UTC. The tool converts between timestamp and human date/time across time zones.
Formula
unix = seconds since 1970-01-01T00:00:00Z
Example
1750000000 → 2025-06-15 14:13:20 UTC.
Notes
- Mind seconds vs milliseconds — JavaScript uses ms (×1000).
- The timestamp itself is timezone-free (UTC); only the displayed date depends on the zone.
