Validations in Ajax canlandar.

Question

 
Here we are using ajax calendar:

1. Booking allowed for the current month from day one until end of the month. Booking pervious days should not allowed. i.e we need to disable pervious dates.
2. booking next month allowed from the day 15 from the pervious month i.e user can book a ticket after 15th date of current month.
3. user can benefit from the camp once a year, means after 365 days he/she can book the camp.
