Snoozing is all about disappearing while you are unable to answer inquiries, etc., @Eva-and-Klaudio0. If you snooze your listing in March, no one will see your listing (and that includes your calendar) during the month of March. You will get no bookings for future months. So, as I understand it:
If there are days/weeks/months you cannot host - block your calendar for those days.
If there is a time period during which you are unable to answer inquiries because you are off hiking in the un-wifi-ed wilderness - snooze your listing.
If you need a break from hosting or your place is undergoing repairs - temporarily unlist/deactivate.
If you are leaving hosting forever, and you really, really mean it - permanently deactivate.
If you are leaving hosting and being a guest forever and you really, really mean it - cancel your account.
Hope this helps!
