Forgive me. I’m not communicating clearly. I have a head cold that is trying to get the best of me!
Yes, Advent is specifically the roughly four weeks leading up to Christmas. However, I think it makes sense to include the Christmas season (to Epiphany though there are a few different traditions regarding just how long Christmastide should be) in your planning. It gives the period from the 1st Sunday of Advent to Epiphany a much more cohesive feel. After all, there would be no advent if Christ had not been born. Indeed, St. Alphonsus has beautiful daily meditations for Advent and Christmas that really pull it all together.
Regarding the feasts. Of course you know that all saints have feasts though all these do not appear on the general calendar. In the period between the 1st Sunday of Advent and Epiphany, there are 25 feasts/Holy Days for very well known saints such as Sts. Andrew, Francis Xavier, Nicholas, Ambrose, Lucy, John of the Cross, Stephen, John, Thomas Becket, Elizabeth Ann Seton, John Neumann, and more I won’t type out. And of course there are the feasts of the Immaculate Conception, Our Lady of Guadalupe, Holy Family, etc.
Being a mother with small children who is trying to bring the liturgical year into my home, I’m trying to figure out which of these days we will celebrate and how. That’s why I asked. I’m sorry for causing confusion. I think your plan to focus on HDOs is a good one.
