There isn't a validation method for just dates?

I’m just validating a date and I’m getting messages like “The date of birth is too late. It must be between 1/1/1880 12:00:00 AM and 4/20/2015 1:27:40 PM.”

Obviously time doesn’t matter here but I can’t find a better validation method than GetDateTime. How have we gone this far unable to just validate a date?
