About Unix Timestamp Converter
Converts between Unix timestamps (the number of seconds since January 1, 1970) and human-readable dates, in either direction.
Enter a timestamp or a date, and the other format updates automatically. A "use current time" button fills in the current timestamp instantly.
Watch whether your timestamp is in seconds or milliseconds — a 13-digit number is typically milliseconds and a 10-digit number is typically seconds (this tool reads anything from 100,000,000,000, which is 12 digits, upwards as milliseconds), and mixing them up gives a wildly wrong date.
Watch: Unix Timestamp Converter in Action
- How do I know if my timestamp is in seconds or milliseconds?
- A 13-digit number is typically milliseconds, while a 10-digit number is typically seconds — mixing them up gives a wildly wrong date, so it's worth checking the digit count before converting.
