Convert a timestamp to a date

Convert Unix timestamps and dates in any timezone

A timestamp converter translates between Unix epoch time — the number of seconds since 1 January 1970 UTC — and the human-readable dates people actually understand. Our free tool converts in both directions, accepts timestamps in seconds or milliseconds, and formats results in whatever timezone you select. That flexibility makes it invaluable when you are staring at a raw epoch value in a log file or database and need to know exactly when something happened.

Timestamps appear everywhere in software: as record creation dates, log entries, token expiries, cache headers, and API fields. They are compact and timezone-independent, but they are impossible to read at a glance. This converter bridges that gap, auto-detecting whether a value is in seconds or milliseconds, and letting you paste a date to get the corresponding epoch value back for use in code or queries.

A live current-time display ticks in real time so you can copy the exact epoch for right now — perfect for testing, seeding data, or setting expirations. Everything is calculated in your browser with no server calls, so your data stays private and the tool keeps working even without a network connection. It is a quick, dependable utility for developers, sysadmins, and anyone who works with timestamps.

Why use Timestamp Converter?

Both directions

Convert Unix timestamps to readable dates and turn any date back into a timestamp with equal ease.

Seconds and milliseconds

Handle classic 10-digit second timestamps and 13-digit millisecond values, with automatic unit detection.

Timezone aware

Format dates in UTC, your local zone, or any region you choose so the same instant makes sense everywhere.

Live current time

A real-time clock shows the current epoch value, ready to copy for testing and record-keeping.

How to use Timestamp Converter

  1. 1

    Choose a direction

    Decide whether you are converting a timestamp to a date or a date to a timestamp.

  2. 2

    Select the unit

    Pick seconds or milliseconds, or let the tool auto-detect based on the number's length.

  3. 3

    Enter your value

    Paste the timestamp or pick a date, then choose the timezone you want the result shown in.

  4. 4

    Read and copy

    The converted value appears instantly and can be copied to your clipboard with one click.

Common use cases

Read log timestamps

Turn cryptic epoch values in server logs into precise, timezone-adjusted dates to reconstruct exactly when events occurred.

Debug token expiry

Convert the exp claim of a JWT or an expiry field into a readable date to confirm whether a token is still valid.

Seed and test data

Grab the current epoch or a specific date's timestamp to populate fixtures, schedules, and test scenarios.

Coordinate across timezones

Translate a single instant into multiple regional times to schedule releases, meetings, or maintenance windows.

Frequently asked questions

What is a Unix timestamp?

A Unix timestamp is the number of seconds that have elapsed since 00:00:00 UTC on 1 January 1970, known as the Unix epoch. It is a compact, timezone-independent way to represent a moment in time, which is why databases, APIs, and log files use it so widely.

What is the difference between seconds and milliseconds timestamps?

Classic Unix timestamps count whole seconds, producing a 10-digit number for current dates. JavaScript and many modern APIs use milliseconds instead, producing a 13-digit number. This tool lets you choose the unit or auto-detects it by length so you always get the correct conversion.

How does the timezone selector affect the result?

The underlying timestamp is always UTC-based, but humans think in local time. Selecting a timezone changes how the tool formats the human-readable date and how it interprets a date you enter for conversion back to a timestamp. This makes it easy to reason about the same instant across regions.

Does the converter update the current time automatically?

Yes. The tool shows a live current Unix timestamp that ticks in real time, so you can copy the exact epoch value for right now with a single click. This is handy for testing, debugging, and generating fresh timestamps for records.

Is this timestamp converter private and offline-capable?

All conversions happen in your browser with no server calls, so your data never leaves your device. Once the page has loaded it continues to work without a network connection, making it reliable for developers working in restricted or offline environments.

Your privacy matters

Timestamp Converter runs entirely in your web browser. Your files, text, and data are never uploaded to any server, never stored, and never seen by us or any third party. This client-side architecture means you can safely process confidential business documents, personal records, and proprietary data without privacy concerns.
