Answer Format: Date of Birth
The Date of Birth answer format will automatically validate the participant's response, including any minimum age restrictions. Additionally, this format requires participants to type in their date of birth. This should be used when saving a response to the DateOfBirth Demographic Field.
The Date of Birth Answer Format is only available using the "Standard Survey V2" survey type.
