About Random Birthday Generator

Random dates are useful test data for anything date-related — a booking system, a database seeded with sample records, or a scheduling app mockup that needs varied, realistic-looking dates rather than the same placeholder date repeated everywhere.

This tool generates random dates uniformly distributed between any start and end date you choose, so every day in the range has an equal chance of being picked. Generate a single date, or up to 20 at once for a full batch of sample data.

Because the range is fully configurable, you can generate dates confined to a specific year, a birthday range for realistic test profiles, or any custom window your test data or scheduling scenario needs.

This is useful for seeding test databases with date fields, generating sample appointment or booking dates, picking a random date for a giveaway drawing, and any mockup or demo that needs believable, varied dates.

How it works

  1. Set a start and end date. Defines the range dates will be picked from, inclusive.
  2. Choose how many dates. From 1 up to 20 at once.
  3. Click Generate. Random dates within your range appear instantly.
