Epoch / Unix Timestamp Converter
Convert Unix epoch timestamps to readable dates and times in any timezone. Convert dates back to epoch timestamps. Understand millisecond vs second timestamps.
Why use a Unix Timestamp Converter?
Unix timestamps — the number of seconds since January 1, 1970 UTC — are the standard way to represent time in software. They appear in log files, API responses, database records, JWT tokens, and cron jobs. Converting a timestamp to a human-readable date (or vice versa) is a daily task for developers and sysadmins. This tool handles both seconds and milliseconds automatically. Pair it with the date difference calculator and timezone converter in the productivity tools category.
Live clock display
The current Unix timestamp in seconds and milliseconds is shown live and updates every second — perfect for copying the current time.
Bidirectional
Convert epoch to human-readable date/time in your local timezone and UTC, or convert a date/time back to an epoch timestamp.
Auto-detects ms vs s
Automatically distinguishes between second-precision and millisecond-precision timestamps by checking the number of digits.
Epoch timestamps for memorable dates
These landmark timestamps are useful for testing, seeding databases, and understanding the epoch scale.
| Date | Epoch (seconds) | Notes |
|---|---|---|
| 1970-01-01 00:00:00 UTC | 0 | The Unix epoch — the origin of time in Unix |
| 2001-09-09 01:46:40 UTC | 1,000,000,000 | One billion seconds — celebrated by Unix geeks worldwide |
| 2009-02-13 23:31:30 UTC | 1,234,567,890 | Memorable sequential timestamp moment |
| 2038-01-19 03:14:07 UTC | 2,147,483,647 | Year 2038 problem — max value for signed 32-bit integer |
