Understanding Unix Timestamps

A Unix timestamp (also called POSIX time or Epoch time) counts the number of seconds elapsed since January 1, 1970, 00:00:00 UTC. This simple integer representation makes it easy to store, compare, and calculate time differences in databases and programming languages.

Many APIs and databases use Unix timestamps for created/updated dates. This tool auto-detects whether your input is in seconds (10 digits) or milliseconds (13 digits) and converts to UTC, local time, ISO 8601 format, and relative time.
