About this tool
Working with epoch time
The Unix timestamp — or epoch time — is how computers prefer to store a moment: a single number counting the seconds since midnight UTC on 1 January 1970. It's compact, unambiguous and free of time-zone confusion, which is why you'll find it in databases, API responses, log files, JWT tokens and almost every programming language. The catch is that a raw number like 1750000000 means nothing to a human, which is exactly what this converter fixes.
In Timestamp to Date mode, paste an epoch value and the tool instantly shows it four ways: your local date and time, the equivalent in UTC, a strict ISO 8601 string for use in code, and a friendly relative phrase such as "3 days ago" or "in 2 hours". It automatically detects whether you've entered seconds or milliseconds — roughly, ten digits versus thirteen — and tells you which it assumed, so you're never caught out by a value that's off by a factor of a thousand.
In Date to Timestamp mode, pick any date and time and get back both the seconds and the milliseconds value, ready to paste into a query or test. A live current timestamp ticks at the top of the page, updating every second, with a one-click button to drop "now" straight into the converter — handy when you need the present moment as an epoch value.
This is a daily utility for developers debugging timestamps in JSON, database administrators reading stored times, and anyone working with logs or APIs. Because it runs entirely in your browser, conversions are instant and nothing you paste is uploaded. Try it above, and reach for the time zone converter when you need to translate a time across regions.
How it works
Three quick steps — no account, nothing uploaded to a server.
Choose a direction
Convert a timestamp to a date, or a date to a timestamp.
Enter your value
Paste a timestamp or pick a date — or tap 'Use now'.
Copy the result
Read it in local, UTC, ISO and relative formats.
FAQ
Frequently asked questions
What is a Unix timestamp?
A Unix timestamp (also called epoch time) is the number of seconds that have elapsed since 1 January 1970 at 00:00:00 UTC, the reference point known as the Unix epoch. It's a compact, time-zone-independent way for computers to store a moment in time, used everywhere from databases and APIs to log files and programming languages.
How do I convert a timestamp to a date?
Paste the timestamp into the 'Timestamp to Date' tab and the converter instantly shows the human-readable date in your local time, in UTC, in ISO 8601 format, and as a relative time such as '3 days ago'. It auto-detects whether the value is in seconds or milliseconds.
What's the difference between seconds and milliseconds?
Classic Unix time counts whole seconds, while JavaScript and many modern systems use milliseconds (thousandths of a second) for finer precision. A seconds timestamp has about 10 digits today; a milliseconds one has about 13. The converter detects the length automatically, but you can see which it assumed.
How do I get the current Unix timestamp?
The page shows a live current timestamp that updates every second, and a button copies it straight into the input for conversion. This is handy when you need 'now' as an epoch value for testing an API, seeding a database, or generating a token.
Is the timestamp converter free and private?
Yes. It's free with no sign-up or limit, and every conversion runs in your browser — no value you enter is ever uploaded or stored.
