How to convert a Unix timestamp

Logs and APIs store time as a number. Here's how to turn a Unix timestamp into a readable date and back.

Open Timestamp Converter

Steps

  • Open the timestamp converter and paste the number.
  • It detects seconds, milliseconds or microseconds automatically.
  • Read the date in your local time and in UTC.
  • Convert a date back to a timestamp by entering it instead.

Seconds vs milliseconds

A 10-digit number is seconds; 13 digits is milliseconds; 16 is microseconds. The converter detects the scale so you don't accidentally land in 1970 or the year 50000.
