About Unix Timestamp Converter
Convert between Unix timestamps and human-readable dates in both directions. A Unix timestamp counts the seconds since January 1, 1970 UTC and is the format most databases, logs, and APIs use to store time, but it is unreadable at a glance. Paste an epoch value to see the exact date and time it represents, or pick a date to get its timestamp, in both your local timezone and UTC. Developers rely on this constantly when debugging logs, testing time-based logic, or working with API responses. The conversion happens instantly in your browser with no data leaving your device.
How to use this tool
- 1Enter a Unix timestamp to see the human-readable date.
- 2Or pick a date and time to get its Unix timestamp.
- 3Copy whichever value you need.
Unix time milestones and pitfalls
Unix time counts seconds since January 1, 1970 UTC (the 'epoch'). It's the backbone of timekeeping in software - logs, tokens, databases, and APIs all use it. A few reference points help you sanity-check values at a glance.
| Timestamp | Date (UTC) | Note |
|---|---|---|
| 0 | Jan 1, 1970 | The epoch itself |
| 1000000000 | Sep 9, 2001 | 10 digits since 2001 - a 10-digit number is seconds |
| 1600000000 | Sep 13, 2020 | |
| 1800000000 | Jan 15, 2027 | |
| 2147483647 | Jan 19, 2038 | 32-bit signed overflow - the 'Year 2038 problem' |
The most common mistake: confusing seconds with milliseconds. JavaScript's Date.now() returns milliseconds (13 digits today), while most APIs use seconds (10 digits). If your converted date lands in the year 56,000 or in 1970, you've mixed the two - divide or multiply by 1,000.
Frequently asked questions
Seconds or milliseconds?
Unix timestamps are in seconds since Jan 1 1970 UTC. This tool also shows the millisecond value used by JavaScript.
What timezone is used?
The tool shows both your local time and UTC so you can pick the right reference.
