Unix Time Conv

Overview

A Unix timestamp is the number of seconds since January 1, 1970 (UTC) — a compact, timezone-free way computers store time. It's everywhere in logs, APIs, and databases, but it's unreadable to humans. This converter turns a timestamp into a normal date and time, and a date back into a timestamp, instantly in your browser with no upload.

How to Use (Step by Step)

1. 1

   Enter a timestamp or a date

   Paste a Unix timestamp to decode, or pick a date and time to encode.

2. 2

   Convert instantly

   The tool shows the matching date (in UTC and local time) or the timestamp value.

3. 3

   Copy the result

   Use the human date for reading, or the number for code, logs, or a database.

How It Works

The tool takes a Unix timestamp (in seconds or milliseconds) and adds it to the 1970 epoch to produce a calendar date and time, shown in UTC and your local timezone. Going the other way, you pick a date and it counts the seconds since the epoch. Because time is stored as a single number, the conversion is pure arithmetic done locally — nothing is sent to a server.

When to Use This

Reading a timestamp from a log file, API response, or database record. Generating a timestamp to insert into code or a query. Checking what local time an event happened at from its UTC timestamp. Debugging why two systems disagree about a time. Converting between seconds and milliseconds when an API expects one. Verifying a token or cache expiry time.
