What is this tool?

Unix timestamps count seconds (or milliseconds) since 1970-01-01 UTC. Developers encounter them in APIs, logs, and databases. This converter switches between Unix values and readable dates, auto-detects seconds vs milliseconds when possible, and shows the same instant in several common timezones.

How to use it

  1. Choose Unix → Date or Date → Unix.
  2. Enter a timestamp or date, or click Now.
  3. Copy seconds, milliseconds, or ISO UTC, and compare timezone rows below.
