How to Add this Calendar to your Google Calendar. We recommend you do this from your Computer/Laptop.
Log onto your Google Calendar, by going to http://calendar.google.com
On the left, you will see "Other Calendars". Click on the small triangle in front of the words to open it to a list.
Copy and Paste the below address into the box that says "Add a Friend's Calendar", then press Enter
Congratulations! The calendar has been added to your calendar, and you will see updates live. Within 15 minutes, you should also be able to see this calendar on your tablet / smartphone.
For other systems, if you require the ICS method to add the calendar, below is the necessary link. You do not need to use this unless your software specifically requires it.
