โฑ๏ธUnix Timestamp Converter
Convert Unix timestamps to dates and dates to timestamps โ two ways, live, with UTC and local time.
Unix timestamp converter โ convert epoch time to date online
Need to make sense of a Unix timestamp? Our free Unix Timestamp Converter translates both ways instantly. Paste a timestampโlike 1700000000โand see the exact date and time it represents, or pick a date and get its Unix timestamp back. Change either side and the other updates live, so you never have to do the math yourself.
It handles the details developers care about: seconds and milliseconds are both supported (and auto-detected), and every result is shown in UTC and your local time, side by side and clearly labelled, along with the ISO 8601 format and a human-friendly "time ago". A live readout shows the current Unix time ticking by, ready to copy in one click. Whether you're debugging logs, working with an API, or storing dates in a database, you'll get the right conversion every time.
Simply enter a timestamp or date to convert instantly. No sign-up, no downloads, no limitsโjust accurate results, privately.
About the Unix Timestamp Converter
Features
Two-Way Conversion
Enter a Unix timestamp to see the date it represents, or pick a date from the calendar to get its Unix timestamp. Either side updates the other instantly โ no button to press.
Seconds & Milliseconds
Auto-detects whether your timestamp is in seconds (10 digits) or milliseconds (13 digits). You can also override the detection manually with the Seconds / Milliseconds toggle.
UTC & Local Time
Every result is shown in both UTC and your local timezone, clearly labelled with your detected timezone name and UTC offset โ so you always know which is which.
ISO 8601 & Relative
Also shows the ISO 8601 string (e.g. 2023-11-14T22:13:20.000Z) and a human-friendly relative form ("3 days ago" or "in 2 hours").
Live Ticker
A live readout at the top of the page shows the current Unix timestamp ticking in both seconds and milliseconds. Copy it in one click with the Copy Now button.
Copy Buttons
Every output field has its own copy button โ UTC string, local string, ISO 8601, seconds timestamp, and milliseconds timestamp โ so you can grab exactly what you need.
Privacy
Timestamps can appear in logs and API responses that contain sensitive data. The Unix Timestamp Converter is fully client-side: it makes no network requests and stores nothing. You can verify this by watching the Network tab in your browser's DevTools โ you'll see no outbound requests when you convert a timestamp.

Yes. It auto-detects whether your timestamp is in seconds or milliseconds, and you can switch manually.
Does it show UTC and local time?
Yes, every result is shown in both UTC and your local timezone, clearly labelled, along with your detected UTC offset.
What other formats does it show?
The ISO 8601 string and a relative "time ago" form, alongside the Unix timestamp.
What's the current Unix time?
A live readout shows the current Unix timestamp ticking in seconds and milliseconds, which you can copy in one click.
Is my data sent anywhere?
