Random Birthday Generator, FAQ

How do I use the Random Birthday Generator?
Set your options if you like, then press Generate. You'll get a random birthday instantly, ready to copy. Sensible defaults mean you can also just hit Generate.
Is the Random Birthday Generator really random?
Yes. Where available, Toolssy uses the browser's Web Crypto API, far stronger than a basic Math.random() call, so your random birthdays are genuinely unpredictable and unbiased.
Is the Random Birthday Generator free, and do you store my results?
It's completely free with no account and no limits, and no, nothing is stored. Everything runs locally in your browser, so your inputs and results are never sent to a server or logged.
