To import this calendar and have it update dynamically as events are updated, you need to copy this link https://trinitycr.org/events/list/?ical=1&custom=1&category=church and paste it in your preferred calendar program. Alternatively, clicking the link will download the ICS file which you can use to add to a calendar. This method will not update dynamically.
