Convert between Unix timestamps and human-readable dates. Unix timestamps represent time as seconds since January 1, 1970 (UTC), and are widely used in programming, databases, and APIs.
Select whether to convert from timestamp to date, or from date to timestamp.
For timestamp to date: Enter a Unix timestamp (seconds or milliseconds since epoch). For date to timestamp: Select a date and time using the picker.
Choose the timezone for the conversion. The tool supports all standard timezones including UTC, your local time, and specific regional zones.
See the converted value in multiple formats including ISO 8601, RFC 2822, and localized date strings.
Convert timestamps to dates and dates to timestamps.
Support for seconds, milliseconds, and various date formats.
Convert between any timezone including UTC.
One-click to get the current timestamp.
See how long ago or until a timestamp.
Be aware of the Year 2038 problem - 32-bit timestamps overflow in January 2038.
Millisecond timestamps have 13 digits; second timestamps have 10 digits.
Some systems use different epoch dates - this tool uses the Unix epoch (Jan 1, 1970).
A: A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It is a simple way to represent time as a single number, making calculations and comparisons easy.
A: Common issues include: using milliseconds instead of seconds (or vice versa), timezone confusion, or using a timestamp from a different epoch. Check if your value has 10 digits (seconds) or 13 digits (milliseconds).
A: The tool shows the current timestamp and updates in real-time. In JavaScript, use Date.now() for milliseconds or Math.floor(Date.now()/1000) for seconds.
A: For 32-bit signed integers, the maximum is 2,147,483,647 (January 19, 2038). Modern 64-bit systems support timestamps far into the future. This tool handles both.
