How to provide validation for Calendar

i want to provide the validation for Calendar,

E.g: Date should only select previous date from 1990. Should not select 2000 or 2015.

You can achieve this by adding a condition that if date selected is greater than 1990 then show "warning message":

To prevent submission you can also add a condition to hide submit button or other required fields.
