Some Churches follow the Liturgical Calendar – a 3 year cycle that takes you through the scriptures systematically. Other Churches depend on their ministry team to select scriptures appropriate to the season and current events. The Liturgical Calendar recognizes that there are patterns in worship (Advent, Christmas, Lent, Easter, Pentecost.) It also offers some balance in that it may cover each Gospel in turn.

For Churches that use a Liturgical Calendar, how do you include that in your web site? Here is one example, taken from one Episcopal Church. It uses the appropriate colors for each Sunday.
