What is a Unix timestamp?
A Unix timestamp counts the number of seconds (sometimes milliseconds) that have elapsed since 00:00:00 UTC on January 1, 1970 — the "Unix epoch." It's the standard way computers store and compare points in time internally, since it's just one number, independent of timezone or calendar formatting.
Seconds vs. milliseconds
Unix time is traditionally in seconds (a 10-digit number today), but many systems — including JavaScript's Date.now() — use milliseconds (13 digits). This tool auto-detects which one you've entered based on digit count.
