I have created an iCloud calendar for Indivisible Elmwood (I am encouraging our sister organizations to make theirs as easy to use). Depending on your browser set-up, the URL below may automatically offer to subscribe when you click it, or you may need to copy it, then paste it into the New Calendar Subscription item in your Calendar program (under the File menu in Apple Calendar, something similar is available in other calendars).
