The Random Time Generator is a free, fast, and flexible online tool that lets you instantly generate random time values within your chosen time range. Whether you're a developer running simulations, a teacher designing timed activities, or a project manager creating randomized schedules, this tool gives you full control over the format and precision of each generated time.

Why Use a Random Time Generator?

Generate Random Times for Software Testing

Developers can use this tool to simulate time-sensitive events, test logging systems, or pre-fill timestamps in mock environments. It's an easy way to introduce unpredictability into your test cases without manually creating time data.

Random Time Assignment for Project Scheduling

Project planners can use random times to distribute task schedules fairly, simulate workflow timelines, or stress-test scheduling algorithms by introducing randomized start or end times.

Make Learning More Engaging with Random Times

Teachers can add excitement to classroom activities by generating random times for quizzes, time-based challenges, or student rotations. It's a fun way to keep lessons unpredictable and dynamic.

How to Use the Random Time Generator

1. Set Your Time Range

Select a start time and end time using the 24-hour format. For example, to generate times between 9:00 AM and 5:00 PM, enter 09:00 and 17:00.

2. Choose Time Precision

Select how accurate your random times should be:

This flexibility is perfect for everything from broad schedules to high-precision testing scenarios.

3. Pick Your Time Format

You can display times in either of the following formats:

4. Generate and Copy

Choose how many random times you want (from 1 to 20), click the "Generate Times" button, and instantly view your results. Click "Copy" to save and reuse them in your application, worksheet, or project.

Time Format Comparison

12-Hour Format (AM/PM)

This format splits the day into two 12-hour periods. For example, 8:15 AM refers to morning, while 3:45 PM is in the afternoon. It's widely used in the U.S. and in casual time displays.

24-Hour Format (Military Time)

This format runs from 00:00 to 23:59 and removes the need for AM/PM. For instance, 15:00 equals 3:00 PM. It's commonly used in transportation, technical systems, and global time standards.

Frequently Asked Questions

Can I generate random times across multiple days?

No. This tool is designed to generate random times within a single 24-hour day. For random date and time combinations, try our Random Date and Time Generator or Random Date Generator.

Are the times truly random?

Yes. Each time is generated using a secure randomization algorithm that ensures every output is independently and randomly selected based on your settings.

Can I control the time zone?

Generated times use your device's local time zone. If you require a specific time zone, consider adjusting the results manually or using them in combination with a timezone conversion script.

How can I use these times in my code or tests?

Paste them directly into your test scripts, mock data, or UI fields. You can also use them to trigger time-based events, test schedulers, or simulate real-time data flows.
