💡 About Unix Timestamps
Unix timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970 00:00:00 UTC, also known as the Unix epoch.
Common Timestamps:
• January 1, 2000: 946684800
• January 1, 2020: 1577836800
• January 1, 2030: 1893456000
Note: JavaScript uses milliseconds for timestamps, while many systems use seconds. This converter supports both formats.
Convert Unix timestamps to human-readable dates and back, with timezone support. Paste a timestamp in seconds or milliseconds to see the date, or pick a date to get its Unix time — computed locally in your browser.
Frequently asked questions
What is a Unix timestamp?
It is the number of seconds elapsed since 1 January 1970 UTC (the "epoch"). It is the standard machine representation of a moment in time — timezone-independent, easy to store and compare — used across databases, APIs and log files.
Is my timestamp in seconds or milliseconds?
Count the digits: current timestamps are 10 digits in seconds and 13 in milliseconds. JavaScript’s Date.now() returns milliseconds, while most Unix tools and APIs use seconds. If your converted date is in 1970 or year 50,000+, you picked the wrong unit.
How do timezones affect a timestamp?
They don’t — a Unix timestamp identifies the same instant everywhere. Timezones only change how that instant is displayed as a local date and time, which is why the tool can show the same timestamp in UTC and your local zone simultaneously.
What is the year 2038 problem?
Systems that store timestamps as signed 32-bit integers overflow on 19 January 2038. Modern software uses 64-bit values and is unaffected, but it is worth knowing when working with legacy systems or embedded devices.
