Timestamp Converter — Epoch to Date and Back
Unix timestamps count the seconds since January 1, 1970 (the Unix Epoch) and power everything from database records to API responses. This free timestamp converter turns any epoch value into local time, UTC, ISO 8601 and relative time — and converts dates back into seconds or milliseconds.
A live clock at the top always shows the current Unix timestamp. Quick-reference buttons jump to the Epoch, right now, the 2038 limit, and the one-billion mark. Everything runs instantly in your browser with no signup.
Both directions, both units
Convert timestamps to dates and dates to timestamps, in seconds or milliseconds. Unit confusion is the most common epoch bug — the unit dropdown removes the guesswork.
Live clock and quick references
Watch the current Unix timestamp tick live, then jump straight to famous reference values like 0 (Epoch) and 2147483647 (the 32-bit 2038 limit) with one click.
Why developers need this
Logs, APIs and databases store times as integers, while humans read dates. When debugging, being able to translate 1705766400 into a real date — or turn next Friday into epoch seconds — saves real time.
How to use
- To convert a timestamp, paste it in, choose seconds or milliseconds, and click Convert to Date.
- To convert a date, pick a date and time, choose local or UTC, and click Convert to Timestamp.
- Copy any result with the built-in copy buttons.
Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It is timezone-independent, which makes it ideal for storing dates in databases.
What is the difference between seconds and milliseconds?
Classic Unix timestamps are in seconds. JavaScript's Date.now() and many modern APIs return milliseconds (seconds x 1000). This tool handles both — pick the right unit before converting.
What is the Year 2038 problem?
Signed 32-bit timestamps max out at 2,147,483,647, which is January 19, 2038. After that they overflow. Modern 64-bit systems are unaffected, and this tool works with any integer size.
How do I get the current timestamp in code?
In JavaScript use Math.floor(Date.now() / 1000) for seconds; in Python use int(time.time()).
Is anything I convert sent to a server?
No. All conversion happens locally in your browser.
