Auto-detects seconds vs milliseconds. ISO 8601 strings also accepted.

Converted

Invalid input.

Now (live)

Cách dùng

  1. 1 Paste a Unix timestamp (seconds or milliseconds) or any ISO 8601 / RFC 2822 date string into the input.
  2. 2 The Converted panel shows the date in every common form, including a relative phrase like "3 days ago".
  3. 3 The Now panel refreshes every second so you can grab the current Unix time at a glance.
  4. 4 Use Copy on any row to push it to your clipboard.

Vì sao dùng công cụ này

  • Auto-detects seconds vs milliseconds — no more accidentally dividing by 1000.
  • Shows ISO, local, UTC, RFC 2822, and a relative form in one view.
  • Live "Now" reference, useful when you need to script the current timestamp.
  • Runs in your browser — no clock skew from a server.

Câu hỏi thường gặp

How does it tell seconds from milliseconds?

Any input ≥ 1e11 is treated as milliseconds. That threshold corresponds to year ~5138 in seconds, but only March 1973 in milliseconds — so it correctly classifies every real-world timestamp.

What does "negative timestamp" mean?

Unix timestamps before 1970-01-01 UTC are negative. The tool handles them — try -2208988800 for 1900-01-01.

Need this value in a different timezone?

Use our Timezone Converter — paste the ISO output, then pick source and target zones.

How do I add hours to this timestamp?

Convert it to ISO, then use the Date Calculator in Add mode for calendar arithmetic.

Unix Timestamp Converter là gì?

A Unix Timestamp Converter is a tool that translates Unix epoch timestamps, in seconds or milliseconds, into human-readable date formats and back. It runs in the browser and outputs ISO, UTC, RFC 2822, local, and relative representations, with a live "Now" panel showing the current timestamp as it updates.
