February 1 has the Principal Feast of “The Presentation of Jesus in the Temple (Candlemas)” which can be observed on the Monday following. The hymn and song selections largely presume you will use the Candlemas readings, but if instead you are using those for the 4th Sunday after Epiphany there are music suggestions for those lections too.
Jane Williams offers reflections on Sunday readings only, so the Epiphany 4 readings apply in that case.
