⏱️ Timestamp ⇄ Date Converter

Convert Unix timestamps to dates and dates to timestamps. 100% free, private and browser-based — no sign-up required.

What is Timestamp ⇄ Date Converter?

A Unix timestamp is the number of seconds that have elapsed since 1 January 1970 (the "epoch"), and it is how most computer systems store dates internally. A timestamp to date converter translates these raw numbers into readable dates and times, and converts human dates back into timestamps.

The tool shows results in local time, UTC and ISO 8601 format, so you can match whatever your application, log file or database expects.

How to Use the Timestamp ⇄ Date Converter

  1. Paste a Unix timestamp and click Timestamp → Date.
  2. Or pick a date and time and click Date → Timestamp.
  3. Use the current-time button to grab the timestamp for now.
  4. Read the local, UTC and ISO results in the output panel.

Features of Our Timestamp ⇄ Date Converter

  • Two-way conversion between timestamps and dates
  • Shows local, UTC and ISO 8601 formats
  • Accepts timestamps in seconds or milliseconds
  • One-click current timestamp

Benefits & Use Cases

Developers debug logs, APIs and databases where dates are stored as epoch numbers. Converting them into readable form — and back again — is a daily task when building and troubleshooting software.

Because everything runs locally, you can convert timestamps instantly without exposing potentially sensitive log data.

Converting data accurately is easy to get wrong by hand, and a single mistake can ripple through everything downstream. The Timestamp ⇄ Date Converter removes that risk by applying the correct rules every time, so the output you copy is dependable. Because it sits alongside our other converters, you can chain conversions and handle mixed data formats in one place rather than juggling several different websites.

Best of all, our Timestamp ⇄ Date Converter runs entirely inside your web browser. Nothing you enter is uploaded or stored on a server, so your data stays private and results appear instantly. It is completely free, requires no sign-up or installation, and it works beautifully on desktop, tablet and mobile alike. The interface supports both light and dark themes and is built with accessibility in mind, so it is comfortable to use for everyone. Bookmark this page and come back to the Timestamp ⇄ Date Converter as often as you need — it will always be here, ready and free to use.

Tips for Getting the Best Results

For the most accurate conversion, double-check that your input is formatted the way the Timestamp ⇄ Date Converter expects before you run it. Small details — an extra space, a missing separator, or the wrong notation — are the usual cause of unexpected output, and correcting them takes only a moment. When you are working with a large batch of data, convert a small sample first to confirm the result looks right, then process the rest with confidence.

Keep in mind that conversion is only as good as the source data you provide. If your figures or encodings need to be exact for a downstream system, verify a couple of results by hand the first time you use the Timestamp ⇄ Date Converter. Once you trust the output, you can rely on it for repeated use, knowing every conversion follows the same consistent, standards-based rules on every run.

FAQ about Timestamp ⇄ Date Converter

What is a Unix timestamp?

It is the count of seconds since midnight UTC on 1 January 1970. It gives every moment a single, timezone-independent number.

Does it accept milliseconds?

Yes. If your timestamp has 13 digits it is treated as milliseconds; 10-digit values are treated as seconds automatically.

Why show UTC and local time?

Servers usually work in UTC while users see local time. Showing both helps you line up logs and user-facing timestamps correctly.

Is the conversion done online?

No. It runs in your browser using your device's clock and timezone, so nothing is sent to a server.
