Birthday Date Generator — Random Date of Birth

This random birthday generator creates valid calendar dates within any year range you choose. Each result is a real, leap-year-aware date — no "Feb 30" nonsense.

Some people use a fake date of birth on low-priority signups to protect personal details. Don't use fake dates to bypass age checks or commit fraud.

Frequently Asked Questions

A random birthday generator creates a random date of birth within a year range you choose. It's useful for testing forms, creating sample data, or building fictional character profiles.
