Paste multiple Unix timestamps or human-readable dates — one per line — into the Batch Timestamp Converter and convert them all at once. Choose your conversion direction (timestamp to date or date to timestamp), select the timestamp unit (seconds, milliseconds, or auto-detect), and pick your preferred output format. Results appear in a table you can copy or download as CSV.

A Unix timestamp (also called epoch time or POSIX time) is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC, not counting leap seconds. It is a universal, timezone-independent way for computer systems to represent a specific moment in time.
A 10-digit number is typically seconds, a 13-digit number represents milliseconds (1/1000th of a second), and a 16-digit number represents microseconds (1/1,000,000th of a second). The Auto Detect option inspects digit length to pick the right unit automatically.
Select your conversion direction (Timestamp → Date or Date → Timestamp), choose your timestamp unit and preferred output format, then paste your values into the input area — one per line. Click Convert and a results table will appear with each converted value.
You can enter dates in ISO 8601 format such as 2024-01-15 or 2024-01-15 08:30:00. The converter parses the date as UTC and returns the corresponding Unix timestamp in seconds.
Systems that store Unix timestamps as signed 32-bit integers will overflow on January 19, 2038 at 03:14:07 UTC — a problem known as the Year 2038 Problem. Modern systems using 64-bit integers are unaffected and can represent dates hundreds of billions of years into the future.
Yes. After converting, the results table shows all your input/output pairs. You can copy the table data or use the CSV export option to download the results for use in Excel or other spreadsheet applications.
Unix timestamps themselves are always UTC-based and timezone-independent. The displayed date and time, however, can vary depending on whether you choose to display it in UTC or your local timezone. This converter displays results in UTC for consistency.
You can choose from YYYY-MM-DD HH:MM:SS, ISO 8601 date only, ISO 8601 date+time, RFC 2822 (email format), and a compact YYYYMMDDHHMMSS format. All formats use UTC as the reference timezone.
