Unix Timestamp Converter

Convert between Unix timestamps and human-readable dates.

Timestamp → Human Date
Date / Time → Timestamp

What does this tool do?

Computers store time as a single integer: the number of seconds elapsed since January 1, 1970, 00:00:00 UTC — known as the Unix epoch. This format is universal and timezone-free, which is why databases, server logs, APIs, and JWT tokens all use it internally. But the number 1700000000 does not tell you much at a glance. This tool converts in both directions: paste a timestamp to see the human-readable date and time, or enter a date to get its corresponding timestamp.

How to use it

  1. To convert a timestamp to a date: type or paste the number into the timestamp field.
  2. To convert a date to a timestamp: use the date and time fields, then click Convert.
  3. The result shows both UTC time and your browser's local timezone.

Pro tips

  • Some systems use milliseconds instead of seconds. If your timestamp is 13 digits long, divide by 1000 first.
  • Unix timestamps are always UTC — remember to convert to local time when displaying dates to users.
Example

Timestamp: 1700000000

UTC: Wednesday, November 14, 2023 at 22:13:20

Your local time will differ depending on your timezone.

When would you use this?

  • Reading the exp (expiry) field from a JWT token — it is always a Unix timestamp
  • Figuring out when a server log entry was created
  • Converting a database timestamp to a readable date for a report
  • Checking when a scheduled job last ran based on its recorded timestamp
