About Epoch Converter
Paste a Unix epoch timestamp and get a date and time a person can actually read, or enter a date and get the epoch number back. It is the quick way to make sense of the timestamps that turn up in logs, API responses, and database rows.
The conversion runs entirely in your browser, so the numbers and dates you enter stay on your own device and are never uploaded to a server. It is free, needs no account, and has no usage limits.
Frequently asked questions
- Is it free, and do I need an account?
- Yes, it is free, and there is no account or sign-up. You can convert as many timestamps as you like, with no usage limits and nothing to install.
- Do the timestamps I enter get uploaded anywhere?
- No. The converter runs entirely in your browser, so everything you type is processed on your own device. Nothing is sent to or stored on a server.
- How do I use it?
- Paste a Unix epoch number to see the date and time it represents, or enter a date to get the epoch number back. The result updates as you go, and you can copy it out.
- What is the difference between seconds and milliseconds?
- A Unix epoch counts the seconds since January 1, 1970, but many systems store it in milliseconds, which is a thousand times larger. If a converted date looks wildly off, check whether your number is in seconds or milliseconds.
- Which time zone does it use?
- Epoch timestamps are counted in UTC, so that is the reference point behind every conversion. A raw epoch number carries no time-zone information of its own, so if you need the exact moment somewhere else, you will have to apply that offset yourself.
