Timestamp Converter - Convert Unix Timestamp to Date Online Free

How to Use the Timestamp Converter

1. Enter a Unix timestamp — type or paste your Unix timestamp (in seconds) into the input field. The converter instantly displays the corresponding date and time in both UTC and your local timezone.
2. Or pick a date — use the date and time picker to select any date. The tool instantly shows the equivalent Unix timestamp in seconds.
3. Get current timestamp — click the “Now” button to grab the current Unix timestamp for immediate use.
4. Copy with one click — click the copy icon next to any result value to copy it straight to your clipboard.
5. Toggle formats — switch between UTC and local time display to see the conversion in your preferred format.

All conversions are done locally in your browser. No data is sent to any server — your timestamps never leave your device.

Features

FAQ

What is a Unix timestamp?

A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (UTC), excluding leap seconds. It is widely used in programming and database systems as a standardized way to store time values.

Does this converter support milliseconds?

The primary input accepts seconds. If you have a millisecond timestamp (e.g., 1718000000000), divide by 1000 first to get the Unix seconds equivalent before converting.

Is the conversion accurate for dates before 1970?

Yes, the converter handles dates before the Unix epoch (before January 1, 1970) and displays negative timestamps for those dates.

Why are there two display formats?

UTC is the universal time standard unaffected by timezone or daylight saving. Local time reflects your device’s current timezone setting. Both are shown so you can use whichever format your application requires.

Tips

• Use the “Now” button as a quick reference when setting expiration times in JWT tokens or session cookies
• Bookmark the page with a timestamp parameter to pre-load specific conversions: useful for debugging production issues by looking up exact event times
