What is a Unix timestamp?
A Unix timestamp is the number of seconds elapsed since 00:00:00 UTC on 1 January 1970 — the 'Unix epoch'. It is how virtually every computer system stores time internally: a single unambiguous number, immune to time zones and date formats. 1,750,000,000 corresponds to June 2025.
A 10-digit timestamp is in seconds; a 13-digit one is in milliseconds (used by JavaScript). This converter auto-detects both and shows the result in UTC and your local time zone.

- How do I know if my timestamp is in seconds or milliseconds?
- A 10-digit number is almost certainly in seconds. A 13-digit number is in milliseconds. This converter auto-detects which format you have entered.
