Timestamp Converter

Convert Unix timestamps to readable dates and back. A Unix timestamp is the number of seconds since 1 January 1970 (UTC) — the standard way computers store time. Paste one in to see the exact date and time in both UTC and your local timezone, or pick a date to get its timestamp. A “now” button grabs the current moment instantly.

How to Use the Timestamp Converter

  1. To convert a timestamp: type the seconds value (for example 0) and click Timestamp → Date.
  2. To convert a date: pick a date and time, then click Date → Timestamp.
  3. Click Now to fill in the current timestamp and see what moment it represents.

Practical example

A log file shows an error at timestamp 1767225600 and you need to know when that was. Paste it in and click Timestamp → Date: you get the UTC time and your local time side by side. Going the other way, pick next Friday at 9:00 AM and get the timestamp to embed in a scheduled API call. Timestamp 0 famously maps to 1 January 1970, 00:00:00 UTC — the Unix epoch. Developers also use this when debugging JWT tokens or cache headers, where expiry times are always stored as Unix timestamps; converting them here instantly tells you whether a token died an hour ago or next year.

Key features and benefits

  • Both directions: timestamp to date and date to timestamp in one place.
  • UTC plus local: results show the UTC moment and your browser’s local time together, so timezone confusion disappears.
  • One-click “now”: capture the current second instantly.
  • Validation: non-numeric or out-of-range input gets a clear message, never a crash.
  • Fully offline: conversion is pure math in your browser — no network needed.
  • Epoch reference: handy for understanding relative times like “3600 seconds from now”.

Limitations

Input is in whole seconds (the classic Unix format); millisecond timestamps with 13 digits need dividing by 1000 first. The date picker works in your local timezone while timestamps are inherently UTC — the tool shows both, but be careful when scheduling across timezones. Dates far outside the 1970–2100 range may behave inconsistently across browsers.
