What is a Random Birthday Generator?

A random birthday generator is a tool that creates random dates of birth within a specified age range. It uses cryptographically secure randomness to ensure every generated date is fair and unpredictable.

Unlike simple random date generators, our tool focuses on realistic birthday generation — you set the age range (e.g., 18–65), and the generator produces dates that correspond to people within that age range today. This makes it ideal for testing, role-playing, and privacy protection.

How to Use

Set the count — Choose how many birthdays to generate (1 to 1000).
Adjust the age range — Set minimum and maximum ages to control the generation.
Pick a format — Choose from ISO, US, European, verbose, or year-only formats.
Generate — Click the button or press Enter to generate instantly.
Copy or download — Copy individual results, copy all, or download as TXT/CSV/JSON.
