About Date to Unix Timestamp
When working with APIs and databases you often need a date as a Unix timestamp. This tool parses each date line and outputs the corresponding epoch seconds. It accepts ISO 8601 and many common date formats the browser understands, and it runs entirely in your browser.
FAQ
What date formats are accepted?
ISO 8601 and common formats the browser's date parser understands, e.g. 2026-06-16 or Jun 16 2026.
Is the output in seconds or milliseconds?
Seconds — divide-down is handled for you; multiply by 1000 if you need milliseconds.
What if a date is invalid?
The line is marked invalid so you can correct the format.
