Local random date generation

Dates are generated in your browser. Raw selected ranges are not sent to analytics.

Generate random dates for real tasks

Use this random date generator when you need calendar dates for test data, classroom examples, writing prompts, mock schedules, content calendars, or one-off decisions. Choose the start and end date, set how many dates you need, decide whether repeats are allowed, and copy the result in a spreadsheet-friendly format.

The generator runs in your browser. It uses browser pseudo-randomness, which is appropriate for everyday utility work and sample data, but it is not a cryptographic or atmospheric true-random service.

Useful random date examples

  • Pick 20 random birthdays between 1980 and 2005.
  • Generate weekdays for a publishing calendar.
  • Create ISO dates for CSV test rows.
  • Choose a random event date in the next 90 days.
  • Make a shuffled list of dates for classroom exercises.

Date formats

ISO dates such as 2026-05-03 are best for databases, CSV files, and code. US dates such as 05/03/2026 are easier for many spreadsheets. Long dates such as May 3, 2026 are better for readable lists, prompts, and planning notes.

FAQ

Can I generate more than one random date?

Yes. Set the count to generate a single date or a list of dates.

Can I exclude weekends?

Yes. Choose the weekdays preset or select custom days so Saturdays and Sundays are excluded.

Can the dates be unique?

Yes. Keep unique dates enabled when you do not want repeats. If the requested count is larger than the available matching days, the tool will show an error.

Are these dates truly random?

The tool uses browser pseudo-randomness. That is suitable for sample data, planning ideas, and everyday random choices. It is not meant for cryptographic security or regulated drawings.

Does it handle leap years?

Yes. Valid calendar dates such as February 29 are handled when they exist in the selected range.

Are my dates saved?

No. Date generation runs locally in your browser, and generated dates are not sent to analytics.
