Epoch Converter - Unix Timestamp Converter

What is Epoch Time?

Every computer tracks time using a single number — the total seconds elapsed since January 1, 1970, 00:00:00 UTC. This number is called epoch time (or unix timestamp), and that starting point is the unix epoch. You'll find this format in server logs, database columns, API responses, and across every major operating system — which is why developers need to convert epoch time to a readable date so often.

This epoch converter is a two-way unix timestamp converter that runs entirely in your browser. Paste a timestamp to see the date, or pick a date to get its epoch value — no signup, no server calls.

How to Convert a Unix Timestamp to Date

The most common task is converting a unix timestamp to date. You have a number like 1718451000 from a log file or API response, and you need to know what date and time it represents.

With this online timestamp converter, just paste the number into the "Epoch Timestamp" field above. The tool auto-detects whether it's in seconds (10 digits), milliseconds (13 digits), microseconds (16 digits), or nanoseconds (19 digits) — and instantly shows the result in local time, UTC, and ISO 8601 format.

The converter handles edge cases too — negative timestamps for dates before 1970, and very large values for far-future dates. Whether you're debugging a linux timestamp from a server or reading an epoch timestamp from a database column, the result is the same: an instant, readable date.

How to Convert a Date to Unix Timestamp

Going the other direction is just as common. You need to store a deadline, schedule an event, or query records after a certain date to epoch value. Use the "Local Date & Time" or "UTC Date & Time" picker above to select your date, and the converter instantly generates the corresponding unix timestamp in seconds, milliseconds, microseconds, and nanoseconds.

You can also type an ISO 8601 string like 2024-06-15T12:30:00Z directly into the ISO field — the tool parses it and fills in all the timestamp formats for you.

Supported Timestamp Formats

Not all systems use the same precision. This epoch unix timestamp converter supports four levels:

• Seconds (10 digits) — the standard unix time in seconds, used by Python, PHP, Ruby, and most linux timestamp systems.
• Milliseconds (13 digits) — used by JavaScript, Java, and most modern web APIs.
• Microseconds (16 digits) — common in high-precision logging and PostgreSQL.
• Nanoseconds (19 digits) — used in performance profiling and scientific applications.

The format is detected automatically based on the digit count — no need to select anything manually.

Common Epoch Time Intervals

When working with unix time, it helps to know the common intervals as a quick reference for your timestamp calculator needs:

Why Use an Online Epoch Converter?

If you're a developer, you've probably run into raw timestamps in log files, database exports, or API responses. Mentally converting 1718451000 to "June 15, 2024" isn't practical. An online timestamp converter like this one gives you the answer in under a second — no need to write a script or open a REPL.

This tool also helps when you need to go from a date to unix timestamp — for example, setting a cache expiry, filtering database records by time range, or generating a UTC timestamp for an API request. The two-way conversion, combined with support for multiple precisions and both local and UTC input, covers virtually every use case.

Everything runs client-side in your browser. Your timestamps are never sent to any server, making this a fast and private unix time converter you can rely on daily.
