What is This Tool?

A date of birth generator creates random realistic birth dates within configurable age ranges. Generated dates follow proper calendar rules (accounting for leap years, month lengths) and can be output in multiple formats including ISO 8601, US (MM/DD/YYYY), European (DD/MM/YYYY), and more.

Realistic DOB generation requires proper age distribution modeling. This tool generates dates that produce ages within your specified range, accounting for the current date to ensure generated ages are always accurate at the time of creation.

Frequently Asked Questions

Can I specify an age range?

Yes. You can set minimum and maximum ages, and the generator will create birth dates that produce ages within that range based on today's date.

Are leap years handled?

Yes. The generator correctly handles leap years — Feb 29 dates are only generated for valid leap years, and age calculations account for leap day boundaries.

What date formats are available?

ISO 8601 (YYYY-MM-DD), US (MM/DD/YYYY), European (DD/MM/YYYY), and long format (Month Day, Year) are all supported.
