Random Date of Birth Generator
Generates a birth date for someone aged 18 to 65, inclusive, as of today.
Date of birth generated locally in your browser with the Web Crypto API. Only the ISO date is copied.
Age-bounded birth dates
Generate a believable date of birth constrained to a realistic age range. The age is computed as full years elapsed as of today — a birthday that has not yet occurred this year counts as one year younger — so the result is always within the range you set.
Useful as mock data for sign-up flows, KYC checks, and 18+ age gating. Everything runs locally on your device; the ages you enter and the dates you generate are never sent to a server.
