How to use Epoch and Unix Timestamp Converter
- See the current Unix timestamp, updated every second.
- Paste a value in Timestamp (seconds or ms) and click To date.
- Read the result as Local time, UTC and ISO format.
- To go the other way, pick a Date & time and click To timestamp for seconds and milliseconds.
Seconds, milliseconds and time zones
A Unix timestamp counts seconds since 00:00:00 UTC on 1 January 1970. JavaScript and many APIs use milliseconds instead. The tool treats any number below 100,000,000,000 as seconds and anything larger as milliseconds, so you can paste either kind without changing a setting.
Local time follows your device's time zone, which is IST (UTC+5:30) for most users in India. The date picker is also read in local time, so 1 January 2026 at midnight on an IST device gives 1767205800, not 1767225600.
Limitations
- Only your device's own time zone and UTC are shown; you cannot pick another zone.
- Millisecond timestamps for dates before March 1973 are below 100 billion, so they are misread as seconds.
- Leap seconds are ignored, as they are in standard Unix time.
Frequently asked questions
How do I tell if a timestamp is in seconds or milliseconds?
A current value in seconds has 10 digits; in milliseconds it has 13. The tool detects this for you.
Why does my converted time differ by five and a half hours?
You are probably comparing local IST with UTC. Both are shown so you can match whichever your system uses.
What is the Year 2038 problem?
Systems storing seconds in a signed 32-bit number overflow on 19 January 2038 UTC. Modern 64-bit systems, and this tool, are not affected.
