FAQ
- What is the difference between seconds and milliseconds timestamps?
- Unix timestamps are traditionally expressed in seconds since January 1, 1970 UTC. JavaScript and many modern APIs use milliseconds, which is the seconds value multiplied by 1000. Use seconds for most server-side systems and milliseconds for JavaScript code.
- What timezone is used for conversion?
- The datetime-local input uses your browser's local timezone. For UTC results, adjust your input accordingly. You can also type ISO 8601 strings with a Z suffix (e.g., 2026-04-01T12:00:00Z) to specify UTC explicitly.
- What date formats can I type manually?
- You can type any format that JavaScript's Date constructor accepts: ISO 8601 (2026-04-01T12:00:00), date only (2026-04-01), or common formats like "April 1, 2026". The tool will parse and convert whatever is recognized.
The Date to Timestamp converter takes a human-readable date and time and returns the corresponding Unix timestamp in both seconds and milliseconds. Supports datetime-local input for easy date picking and manual text entry for ISO 8601 strings. The reverse of the Unix Timestamp to Date converter.
