Pro Missa is Latin. It means "Before the Mass." It is a modular system for everything you can do with the times of a celebration. The system includes a modular schedule. Through the webshop module, Mass intentions can be ordered on your parish site. These are collected in a document which is printed for use in the celebration. With handy widgets the current Mass times are placed on the website. Users can also add the schedule to their own calendar so that they no longer have to manually add it to their digital calendar.
