What is a timestamp converter?
A timestamp converter turns Unix timestamps (seconds or milliseconds since 1970-01-01 UTC) into human-readable dates and times, and vice versa. It can also parse ISO 8601 date strings (e.g. 2024-03-10T12:00:00.000Z) and convert them to timestamps.
Why this tool is useful
APIs, logs, and databases often store time as numbers. Debugging or reporting is easier when you see the actual date. This tool converts both ways: paste a timestamp to get a date, or paste an ISO date to get a timestamp. Invalid input shows an error. All conversion runs in your browser.
Example usage
Enter 1710000000000 (Unix ms) and choose To date to see the ISO date and time live. Choose To timestamp and paste 2024-03-10T12:00:00.000Z to get the millisecond value. Use it for log analysis, API debugging, or quick date math.
How to use this tool
Type a Unix timestamp (e.g. in milliseconds) or an ISO date string in the input box. Choose To date or To timestamp; output updates as you type. Copy the result or clear and try another. For other dev utilities try UUID Generator or JSON Formatter.
