To add any of the calendars to your own Google Calendar, click the Calendar (plus button) in the bottom right corner of the calendar box.
If presented an option, select to open in a browser, then log in (if not already) to the Google account where you would add the calendars. (If it opens in Google “Calendar” app on mobile devices, it won’t work!)
Next, select which calendars you wish to add. You may always hide or remove any at any time later. (Additional steps may be required to display newly added calendars on synchronized mobile devices.)
If you don’t use Google calendar, and these won’t add it to your other (Apple, Outlook, etc.) digital calendar, we will try to provide other links that will work.
