About Timestamp Converter
Make a Unix timestamp readable, or turn a date into seconds or milliseconds for another tool.
How to use it
- Choose Unix → date or Date → Unix, then select seconds or milliseconds.
- Enter a timestamp, or an ISO date with Z or an explicit timezone offset, such as 2026-01-01T00:00:00Z.
- Run the tool and check the UTC date and unit-labelled results.
Good to know
- Units are explicit; the tool does not guess whether a value is seconds or milliseconds.
- Date input must include a timezone. Output uses UTC, and precision is limited to milliseconds.
Your tool input is processed in this browser and is not uploaded by the application. JavaScript is required to run the tool.
