Random Date Generator
Generate a random date between two dates you specify. Perfect for test data, games, and random event scheduling. Free, instant.
How to use this tool
- Set the start and end dates for your desired range.
- Choose how many dates to generate.
- Click Calculate to generate random dates.
- Dates are output in YYYY-MM-DD format.
- Click again to generate a fresh set.
Generate random dates within a specified range — useful for generating test data, picking random calendar dates for scheduling, or creating fictional timelines.
How it works
This tool picks one or more dates at random from within a range you define. Set a start date and an end date, choose how many dates you need, and the generator returns that many random calendar dates spread across the range.
Every date in the range has an equal chance of being selected. If you request multiple dates, duplicates are possible unless your range is narrow; for unique dates, request fewer dates than the number of days in the range.
Common uses include generating realistic test data for software development, picking random draw dates for contests, or assigning random event days for tabletop games and simulations.
Worked example
Generate 5 random dates within a calendar year for test data
- Set Start date to 2024-01-01.
- Set End date to 2024-12-31.
- Set Number of dates to 5.
- Click Generate.
Five random dates such as 2024-03-14, 2024-07-02, 2024-09-21, 2024-11-05, 2024-04-30.
Common mistakes to avoid
- Entering end date before start date -- always put the earlier date in the Start field.
- Requesting more unique dates than days in the range -- this can cause duplicate results.
- Forgetting to account for timezone differences when using the dates in code.
Key terms
- Date range
- The span of calendar dates between the start date and end date, inclusive.

- Each date in the range is equally likely to be chosen.
Frequently asked questions
- What format are the dates in?
- Dates are output as ISO 8601 strings: YYYY-MM-DD (e.g. 2025-07-14).
- What if I enter the end date before the start date?
- The generator automatically swaps them so the earlier date is always the start.
- Can I generate dates in a specific month only?
- Set both start and end to the same month, e.g. 2025-03-01 to 2025-03-31.
