I'm glad you like our site, thanks! You can use the Swiss Transfer Ticket from either Zurich airport or Zurich HB (the central station in town) to travel to Zermatt. Doing so two days after your arrival is no problem. Should you be asked for a travel date when you buy it, enter the actual travel day, not the day of arrival. A listed of trusted resellers can be found here.
Enjoy your stay in Zermatt and Zurich!
