Do you mean why on the calendar of your listing, the date are open for the next 12 months ?
if yes, it is because this is the option you have selected in your add.
to change it, go in your add, in parameters, then calandar, then calendar parameters. It should be called something like calendar availability… I’m not sure if the exact wording as my app is in French.
good luck
