What is a Unix timestamp?
A Unix timestamp is a count of time from the Unix Epoch: January 1, 1970 at 00:00:00 UTC. Most systems use it to store, compare, sort, and transfer time without depending on a user's local timezone.
| Human readable time | Seconds |
|---|---|
| 1 minute | 60 seconds |
| 1 hour | 3,600 seconds |
| 1 day | 86,400 seconds |
| 1 week | 604,800 seconds |
| 1 month (30.44 days) | 2,629,743 seconds |
| 1 year (365.24 days) | 31,556,926 seconds |
Seconds vs milliseconds
APIs often use seconds, while JavaScript Date uses milliseconds.
Always think UTC
The timestamp itself is timezone-neutral; formatting creates local time views.
Common use cases
Logs, expiry times, cache keys, scheduled jobs, and database sorting.
