Timestamp Converter
Convert Unix timestamp to readable date and convert date back to timestamp instantly.
About This Tool
The Timestamp Converter tool helps you convert timestamps into human-readable date and time, and also convert a date/time back into a timestamp. It is commonly used for Unix timestamps (seconds or milliseconds since 1 Jan 1970).
This tool is useful for developers, analysts, and anyone working with logs, APIs, databases, analytics tools, or server events where timestamps are shown as numbers.
It can help you quickly understand when an event happened, compare times, debug API responses, and format dates correctly.
How To Use
- Paste your timestamp value into the input (example:
1700000000or1700000000000). - Select the unit: seconds or milliseconds (if auto-detect is available, it will detect automatically).
- View the converted date/time instantly.
- To convert date → timestamp, enter a date/time and generate the timestamp output.
Still Have Questions?
It is the number of seconds (or milliseconds) passed since January 1, 1970 (UTC).
Seconds are usually 10 digits (e.g., 1700000000). Milliseconds are usually 13 digits (e.g., 1700000000000).
Most converters can show both UTC and local time depending on your selection.
It may be a timezone difference (UTC vs local), or the timestamp might be in milliseconds instead of seconds.
