About Unix Timestamps

Unix timestamp is the number of seconds since January 1, 1970, 00:00:00 UTC (the Unix epoch).

Note: Some systems use milliseconds instead of seconds. JavaScript uses milliseconds, while most databases use seconds.

Common Ranges:
• 1970s: 0 - 315,532,800
• 1980s: 315,532,800 - 631,152,000
• 2000s: 946,684,800 - 1,262,304,000
• 2020s: 1,577,836,800 - 1,893,456,000

Timestamp Converter FAQs

Does the tool accept millisecond timestamps?

Yes. Values are detected automatically: numbers of roughly ten billion and above are treated as milliseconds, while smaller values are read as seconds. Both the seconds and milliseconds forms are shown in the results.

Which output formats are produced?

Local time in your browser timezone, UTC time, ISO 8601 notation, and a relative description such as "3 hours ago" or "2 days from now", plus the timezone name and the day of the year out of 365 or 366.

Can I convert a date back into a timestamp?

Yes. Switch to the Date to Timestamp mode, pick a date and time in your local timezone, and the matching Unix value appears. The Current Time button fills in the present moment in either mode.

What do the example timestamp buttons show?

Four landmark values: the Unix Epoch (0, midnight January 1, 1970), Y2K (946684800), one billion (1000000000, September 2001), and the 32-bit maximum of 2147483647, the famous January 2038 boundary.

Do conversions depend on my device settings?

Local times and the detected timezone come from your browser locale, while UTC and ISO output are absolute. All the math happens in the page with no network calls.
