If you're a member of St. Joseph's and have an event to add to the calendar, you can email it to office@stjosephofarimathea.org or, if you have login credentials, you can add them to the appropriate calendar here: My SJA (St. Joseph of Arimathea)
There are actually several calendars included on this page. Red items are Church events, green items show times when community organizations have reserved portions of the church facility, gold items are part of the Kalendar (feasts & fasts of the Church). National holidays are shown in light blue. If you'd like to see only one calendar, you can deselect others at the drop down menu that appears when you click the arrow to the right of "agenda."
