Date of birth formats
The generator produces dates of birth in the Dutch date format: DD-MM-YYYY (day-month-year).
When using these as test data in software, you can easily convert the format to other notations such as ISO 8601 (YYYY-MM-DD), the American format (MM/DD/YYYY) or a Unix timestamp. The generator ensures that all dates are valid (no February 29 in non-leap years, correct month lengths).
Frequently Asked Questions
How does the date of birth generator work?
The generator creates random dates within the specified age range. You set a minimum and maximum age, and the generator picks a random date between those boundaries. The result is displayed in date format (DD-MM-YYYY).
Can I adjust the age range?
Yes, you can set both the minimum age and the maximum age. By default, the tool generates dates for persons between 18 and 80 years old. You can adjust this to any desired range, for example 0-17 for minors or 65-100 for retirees.
What format are the dates of birth generated in?
All dates of birth are generated in the format DD-MM-YYYY (day-month-year). When exporting to JSON or CSV, you can easily convert the format to other notations in your own code.
What do developers use fictional dates of birth for?
Developers use fictional dates of birth for testing age validation (18+ checks), filling test databases with realistic personal data, form validation, testing date pickers and date parsing, and generating complete test profiles in combination with the BSN and name generator.
Can I generate dates of birth in bulk?
Yes, you can generate up to 10,000 dates of birth at once and export them directly to Excel (.xlsx), CSV, or JSON. All generation takes place client-side — no data is sent or stored.
