Ordinary Time

Ordinary Time (Latin: Tempus per annum) is the part of the liturgical year in the liturgy of the Roman Rite, which falls outside the two great seasons of Christmastide and Eastertide, or their respective preparatory seasons of Advent and Lent. Ordinary Time thus includes the days between Christmastide and Lent, and between Eastertide and Advent. The liturgical color assigned to Ordinary Time is green. The last Sunday of Ordinary Time is the Solemnity of Christ the King.

The word "ordinary" as used here comes from the ordinal numerals by which the weeks are identified or counted, from the 1st week of Ordinary Time in January to the 34th week that begins toward the end of November.
