How do I make my calendar available on a fixed date for example every month and not 30 days out?

I am new to Square and I'm trying to figure out how I can allow customers to book appointments for a set timeframe for example January 1-March 1 and not 60 days out? 60 days out is very annoying and would require me to constantly update my personal availability versus making sure I have everything in order and ready for the date that I want to publish the calendar for.
