Hi @Vijay Prakash,

You don't want give future dates in Calendar or you want to validate the future date in Calendar? We have different ways,

If you don't want give future dates in Calendar --> Presentation TAB just disable the next  or else give 0 value.

or We edit validate rules, for to validate the date for the future date: 

Rule Name Edit Validate : NotFutureDate  (this used to check the given date is past or not, if the given date is past it will not throw any error, if it is future date it will throw an error)

Thanks,

Ashok
