If your calendar app supports subscribing to internet calendars (the WebCal protocol), then copy and paste the WebCal link into your calendar app. It is recommended to subscribe as the calendar will refresh automatically when fixtures change. If you are not familiar with how to add a calendar subscription to your calendar then you may need to seek help for your specific app. These apps support the WebCal protocol:

All fixtures for the current season are included. By default the event duration for a game is 90 minutes. If there is no start time then the event will be shown as a free/not busy all day event until the time is allocated. Select 'Always' below if you want events to always be shown as free/not busy. The event description will include result after game is played. The default for the event summary (subject/title) is 'Hockey Fixture' with a suffix to indicate whether game is home (H) or away (A). You may change this default by selecting your preferred Subject/Title below.

If you are unable to subscribe, click on Download Calendar to get an iCalendar (.ics) file with team fixtures listed as events. Opening the downloaded iCalendar file will open your default calendar app, or you may open your preferred calendar app and find the import or upload feature to add events from the file to your calendar. The download is only a snapshot so when fixtures are changed or added then you must repeat the process.
