Frequently Asked Questions
How do I convert a Unix timestamp to a date online?▾
Enter your Unix timestamp (in seconds or milliseconds) into the input field and click "Convert to Date". The tool instantly shows the date in UTC, local time, ISO 8601 format, and relative time.
What is the difference between seconds and milliseconds timestamps?▾
A Unix timestamp in seconds (e.g., 1700000000) counts seconds since January 1, 1970. Millisecond timestamps (e.g., 1700000000000) count milliseconds. This tool auto-detects which format you enter.

Yes. Enter any date string such as "2023-11-14T22:13:20Z" or "Nov 14 2023" and click "Convert to Timestamp" to get both the seconds and milliseconds Unix timestamps.
