What is a Unix Timestamp?
A Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC (the Unix Epoch), not counting leap seconds. It's the standard way to represent time in programming, databases, and APIs. Unix timestamps are timezone-independent — the same timestamp represents the same moment worldwide.
Common Timestamp Reference
| 0 | 1970-01-01 00:00:00 UTC (Unix Epoch) |
| 1000000000 | 2001-09-09 01:46:40 UTC |
| 1234567890 | 2009-02-13 23:31:30 UTC |
| 1500000000 | 2017-07-14 02:40:00 UTC |
| 1600000000 | 2020-09-13 12:26:40 UTC |
| 1700000000 | 2023-11-14 22:13:20 UTC |
| 1800000000 | 2027-01-15 08:00:00 UTC |
Seconds vs Milliseconds
Unix timestamps can be in seconds (10 digits for current dates) or milliseconds (13 digits). This converter auto-detects which format you're using. JavaScript and many APIs use milliseconds, while Unix/Linux systems traditionally use seconds.
