When you are building or testing systems that work with dates and times, you often need realistic but fake data. The Random Date & Time Generator makes that easy by generating random dates within a chosen range and random times of day in both 24-hour and 12-hour formats.
The generator at /date-tools/random-date-time-generator is designed to:
14:23:05.02:23:05 PM.Everything runs entirely in your browser, so you can safely use it even with ranges based on real-world constraints.
/date-tools/random-date-time-generator.If you see an error instead:
14:23:05.02:23:05 PM.Each click produces a fresh random time.
When you create seed data for:
You can use the generator to:
Combined with tools like Random Number Generator and UUID Generator, you can create full fake datasets quickly.
Forms and APIs that accept dates and times need robust validation:
Static mockups and demos look more convincing with diverse sample data:
Randomly generated values are more realistic and less biased than reusing the same example over and over.
If the end date is earlier than the start date, the tool raises an error instead of generating a date. Always:
The generator is intended for ad-hoc testing and demo data. It does not offer:
For repeatable or security-critical randomness, use appropriate libraries in your application code.
It generates random calendar dates within a user-defined range and random times of day in both 24-hour and 12-hour formats, making it easy to create realistic test and demo data.
For dates, you must provide a start date and an end date using the date pickers. For times, there is no input; the tool simply picks a random time within a 24-hour day each time you click the button.
Randomness is produced in the browser using JavaScript’s random facilities and secure random values where available. The tool selects a random point between the start and end dates for dates, and random hours, minutes, and seconds for times.
No. All random generation happens in your browser. The date ranges and generated values are never uploaded, logged, or stored on a backend service.
Use it when you need believable yet fake dates and times for:
Errors appear when one of the dates is invalid or when the end date is earlier than the start date. Correct the range so that both dates are valid and the end date is greater than or equal to the start date.
