Our system allows customers to book rentals several days in advance. This feature ensures that customers can plan their rentals ahead of time and guarantees availability for their desired dates.

For example, I want to make a booking 30 days in advance.

Front-end :

When you choose 30 days, customers can book before 30 days, and the calendar shows the enabled date.

You can change the number of days that you offer your customer.
