Unix Timestamp to Date Converter
Convert a Unix timestamp in seconds into a readable UTC date and time.
How to use Unix Timestamp to Date Converter
1. Enter Unix Timestamp, Timestamp Unit. 2. Whole signed timestamps; seconds multiply by 1000. The supported ECMAScript range is ±8,640,000,000,000,000 milliseconds. Z denotes UTC; leap seconds are not modelled. 3. Select Convert or press Enter. 4. Select Copy result to copy the answer, or Reset to clear the form and result.
Why use this tool?
Whole signed timestamps; seconds multiply by 1000. The supported ECMAScript range is ±8,640,000,000,000,000 milliseconds. Z denotes UTC; leap seconds are not modelled.
How the calculation works
Convert signed epoch seconds or milliseconds to an ISO UTC timestamp. Whole signed timestamps; seconds multiply by 1000. The supported ECMAScript range is ±8,640,000,000,000,000 milliseconds. Z denotes UTC; leap seconds are not modelled. Counts and dimensions use the declared rounding convention; other numbers display up to three decimal places where applicable. Nonzero subsecond durations are labelled. Durations round to the nearest second; nonzero subsecond durations are labelled. File-size output units are decimal. Changing an input label does not convert filled values.
Example
Worked example: Unix Timestamp = 0; Timestamp Unit = "seconds". Result: 1970-01-01T00:00:00.000Z.
Practical tip
Check the input labels and assumptions against the unix timestamp to date task before reusing the number.
