The Church Year continually evolves. In the first couple centuries the anniversaries of the deaths of martyrs were remembered, and many of those early saints are still on our Church calendar, such as Saint Lawrence on August 10. The list gets longer with each new decade.
Robert Taft, S.J. suggested each parish church having its own calendar of local saints. Who has been known for their lives of prayer and good deeds? The day of their death becomes their birth into eternal life, which becomes their day on the parish calendar. You may like to start your own calendar for the family and friends and coworkers who have gone before you. Periodically flip through the pages and pray the names aloud. “Saint N.N., pray for us.” This becomes your own Litany of the Saints.
