Current epoch

Epoch (seconds or ms)

Enter epoch in seconds (10 digits) or milliseconds (13 digits)

Converted Date

How it works

  1. Use Epoch → Date to enter a Unix epoch (seconds or milliseconds) and see the human-readable date.
  2. Use Date → Epoch to pick a date and get the epoch in seconds and milliseconds.
  3. Current epoch updates every second at the top.

What is Unix epoch?

Unix epoch (or Unix time) is the number of seconds since January 1, 1970 00:00:00 UTC. Milliseconds are the same value × 1000. Many systems use it for timestamps.

Examples

  • 0 = January 1, 1970 00:00:00 UTC
  • 1609459200 = January 1, 2021 00:00:00 UTC
  • 1735689600 = January 1, 2025 00:00:00 UTC
