Hello @Linda4875 and welcome 😊
I have just gone onto your new listing and your calendar is open as of today so guests can book your place well before June!!
You need to block all the days before you really want to host by going onto the host calendar and under Settings on the right hand side:
==>Click on Availability
==>select all the dates that you don't want booked (they will turn to black) and choose the option of blocked for all these dates.
Do this quickly as you don't want to start your hosting career with the need to cancel a reservation.
Good luck and if you get really stuck, put your lisitng on pause which will give you time to do this,
Joëlle
