I using yup for validation and using imask for masking a input but I found some issue on validate a date that valid in each month then I notice that when user input a invalid date like 31 of the 4 month that doesn't exist and using new Date() function to create a new date from that it not return any error instead it will return 1st day of month 5 , that mean you can using that as a condition if user input month 4 but you got month 5 for comparing that mean user input invalid date. BTW it may have a proper way to validate that non exist date via yup library.

I still openly for suggestion and any comment feel free to tell me how I can code this better ;)
