Convert Unix timestamps to UTC dates and ISO 8601 dates to seconds or milliseconds.
Choose whether the value is in seconds or milliseconds.
Enter a value to convert it.
Dates are shown in UTC. Conversion runs in your browser.
A Unix timestamp counts time from 1970-01-01 00:00:00 UTC. APIs commonly use seconds or milliseconds.
Convert a timestamp to an ISO 8601 date, or convert a timezone-qualified ISO date back to both timestamp units. Requiring a timezone avoids silently interpreting the date in your local time zone.
Check API values, compare log times, or prepare date values for a request or database.
