The Random Date and Time Generator is a powerful online tool that lets you generate random date and time combinations in various formats. Whether you're a software developer, data analyst, teacher, or event planner, this generator allows you to create random date-time values tailored to your specific needs.
Unlike separate tools, this random date and time generator combines both elements—date and time—into a single output, offering more precision and saving you time.
If you only need a random date, try our standalone Random Date Generator. For time-only use cases, check out the Random Time Generator.
Why Use a Random Date and Time Generator?
For Developers & QA Testers
Use this random date and time generator to simulate log entries, test app behavior at different moments, or populate time-sensitive database fields. Set custom ranges to cover edge cases like year-end rollovers or daylight saving changes.
For Data Scientists & Analysts
Quickly generate training data with realistic datetime values for trend analysis, machine learning models, or statistical sampling. The format flexibility ensures compatibility with various systems.
For Teachers & Students
Bring randomness into classroom projects—create surprise quiz times, randomized historical events, or practice problems involving time intervals.
For Event Planners
Randomly assign meeting slots, appointment times, or event start times within a defined date range. This tool helps simulate real-world schedule planning.
How the Random Date and Time Generator Works
Step 1: Select a Date Range
Choose from three built-in options:
- This Year (default)
- Last Year
- Next Year
Or, switch to Custom Range mode to enter your own start and end datetimes.
Step 2: Choose a Date-Time Format
This random date and time generator supports 10+ common formats, including:
- MM/DD/YYYY HH:mm:ss: e.g., 01/19/2025 14:30:05
- DD/MM/YYYY HH:mm:ss: e.g., 19/01/2025 14:30:05
- YYYY-MM-DD HH:mm:ss: e.g., 2025-01-19 14:30:05
- Month DD, YYYY HH:mm:ss: e.g., January 19, 2025, 14:30:05
- Mon DD, YYYY HH:mm:ss: e.g., Jan 19, 2025, 14:30:05
- Weekday, Month DD, YYYY HH:mm:ss: e.g., Saturday, January 19, 2025, 14:30:05
- MM/DD/YYYY hh:mm:ss AM/PM: e.g., 01/19/2025 2:30:05 PM
- DD/MM/YYYY hh:mm:ss a.m./p.m.: e.g., 19/01/2025 2:30:05 p.m.
- YYYY-MM-DD hh:mm:ss AM/PM: e.g., 2025-01-19 2:30:05 PM
- Month DD, YYYY hh:mm:ss AM/PM: e.g., Saturday, January 7, 2025, 2:30:05 PM
It supports both 24-hour and 12-hour AM/PM output, making it versatile across technical and casual use cases.
Step 3: Set the Quantity
Enter how many date-time values you want to generate. The generator allows up to 20 random results per batch for fast creation.
Step 4: Generate and Copy
Click Generate Random Date & Time and your results will appear instantly. Use the built-in copy buttons to export individual values.
Frequently Asked Questions
Are the generated results truly random?
Yes. Our tool uses JavaScript's secure random number generation to ensure unbiased, unpredictable datetime results.
Can I generate random date-times across decades?
Absolutely. Use the Custom Range mode to set any starting and ending date—even years apart.
Does this support unique results only?
Not by default. Results may repeat. For guaranteed unique outputs, generate smaller batches or filter duplicates manually.
Can I sort the results or export them?
Results can be copied, and you can paste them into spreadsheets or apps. Sorting/export enhancements are coming soon.
Which time zone does the generator use?
Results are generated in your device's local time zone. If needed, you can convert output after copying.
