Convert Unix timestamps and dates.
Convert Unix timestamps to readable dates or turn a date and time into seconds or milliseconds. Compare UTC and local time with a live current timestamp.
Convert Unix timestamps to readable dates or turn date and time values into Unix seconds and milliseconds with UTC, local time and automatic unit detection.
About This Tool
ToolsFaction Unix Timestamp Converter helps developers translate Unix time into readable date values and convert dates back into Unix timestamps. It supports timestamps in seconds and milliseconds, includes automatic unit detection and displays both UTC and local representations.nnA live current Unix timestamp is included for quick reference. Date-to-timestamp conversion can interpret the entered value as local time or UTC, making the tool useful for APIs, logs, databases, scheduled jobs and debugging time-based data.
How to Use
- Enter a Unix timestamp and choose Auto Detect, Seconds or Milliseconds, then select Convert to Date.
- For the reverse conversion, choose a date and time and select whether it should be interpreted as Local Time or UTC.
- Review Unix seconds, Unix milliseconds, UTC and local date values in the result panel.
- Use Current Time for a live reference or copy the complete conversion result when needed.
Example
Enter 1767225600 as seconds to convert it into a readable date, or choose a date and time to generate both Unix seconds and milliseconds.
Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp represents time as the number of seconds that have elapsed since the Unix epoch at 1970-01-01 00:00:00 UTC.
Does the converter support milliseconds?
Yes. You can explicitly choose milliseconds or use Auto Detect for common Unix timestamp lengths.
How does automatic unit detection work?
Auto Detect treats sufficiently large absolute integer values as milliseconds and smaller common Unix values as seconds.
Can I convert a date using UTC instead of local time?
Yes. Date to Timestamp includes Local Time and UTC interpretation options.
Why can local time differ between users?
Local time is formatted using the time zone and locale settings of the browser or device running the tool.
Does the current timestamp update live?
Yes. The current Unix time display updates every second while the tool is open.
Is conversion performed in the browser?
Yes. Timestamp and date calculations run directly in your browser.
