Convert Unix Timestamps Online

Unix time represents a point in time as the number of seconds elapsed since January 1, 1970 at 00:00:00 UTC. It is widely used by operating systems, APIs, databases and software applications.

Seconds or milliseconds

Traditional Unix timestamps use seconds. JavaScript and some APIs commonly represent timestamps in milliseconds, so HandyKitz supports both formats.

UTC and local time

A Unix timestamp identifies the same instant worldwide. HandyKitz can display that instant in UTC as well as your browser's local timezone.

Private browser-based conversion

Timestamp conversion happens locally in your browser and does not require sending the entered values to HandyKitz.

Practical example

Select seconds or milliseconds to match your source. A timestamp describes one instant; its displayed local date and time depend on your browser's timezone.

In seconds mode, 1704067200 corresponds to 2024-01-01T00:00:00.000Z. The same instant in milliseconds is 1704067200000.

Frequently asked questions

Why does my timestamp show a date near 1970?

A millisecond timestamp interpreted as seconds, or the reverse, gives a very different date. Check the source system's unit and select the matching option.

Can I enter a fractional timestamp?

The timestamp field accepts whole numbers only. Use the milliseconds option to represent sub-second precision as an integer.

Which timezone does the date input use?

The date-and-time input is interpreted in your browser's local timezone. It is not a UTC input; daylight-saving transitions can affect local clock times.
