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.
