Milliseconds to date

Convert milliseconds to human readable date. Enter timestamp in milliseconds (e.g. 1704067200000).

Guide to millisecond timestamps

Millisecond timestamps are the most popular format used in modern web applications and JavaScript. Each millisecond is one thousandth of a second, which provides greater precision than traditional seconds. JavaScript (Date.now()) and JVM return time in this format, making it the de facto standard for most web platforms.

JavaScript and timestamps

In JavaScript, Date.now() returns timestamp in milliseconds since epoch 1970. Unlike other languages, JavaScript doesn't have a built-in Date object supporting nanoseconds. To get greater precision, programmers use performance.now() which returns fractional milliseconds with microsecond accuracy.

Applications requiring milliseconds

Millisecond precision is critical in: trading systems where order execution sequence matters, web application performance profiling, browser animations and games for 60+ FPS smoothness, IoT systems collecting sensor data in real-time, and event logging for incident analysis.

Casting and conversion

To convert milliseconds to other formats, remember: divide by 1000 for seconds, divide by 1,000,000 for nanoseconds, divide by 1000 * 60 for minutes, etc. Windows .NET and other systems may use a different epoch - always check the documentation.
