Random Birthday / Date of Birth Generator
Generate random birth dates within any age range — with zodiac sign and day of week.
Generating a random birth date within a chosen age range is useful for test data, demo profiles, or filling out placeholder content without using anyone's real information.
What the extra details (zodiac, day of week) are for
Beyond the date itself, this shows the resulting day of the week and zodiac sign — useful context if your test data or demo profile needs to reference those details consistently alongside the generated birth date.
Frequently asked questions
Is the generated date evenly distributed across my chosen age range?
Yes — the calculator picks randomly within your specified minimum and maximum age, so ages across the full range are equally likely to appear.
Can I use this for a real form that requires my actual birthday?
No — this generates fictional data for testing and demo purposes only, not a substitute for your real information on any form that requires accurate data.
