Timestamp Converter
Convert Unix timestamps to readable dates and back.
Log lines, database rows and API responses are full of epoch numbers that nobody can read at a glance. The Timestamp Converter turns a 10-digit or 13-digit Unix timestamp into readable dates, and turns a date and time back into a timestamp. It runs locally in the app, with no page to open and nothing uploaded.
Seconds and milliseconds
Paste a 10-digit timestamp for seconds or a 13-digit one for milliseconds. Other lengths are rejected with a clear error message.
Six result formats
See Unix seconds, Unix milliseconds, ISO 8601, a UTC string, your local time and a relative description such as "3 days ago".
Two-way conversion
Edit the timestamp or use the date and time picker. Whichever you change, the other field and the results update.
Copy each value
Every result has a copy button, so you can paste the ISO string or milliseconds value straight into code.
Set current time
One button fills in the current time so you can grab a fresh timestamp.
How do I convert a Unix timestamp to a date?
Paste the timestamp into the timestamp field. The tool treats 10 digits as seconds and 13 digits as milliseconds, then shows the ISO 8601, UTC and local representations.
Does it support timestamps in milliseconds?
Yes. A 13-digit value is read as milliseconds, and the results show both the seconds and milliseconds forms.
