January 1); in those years when the Epiphany falls on January 7 or January 8, the Baptism of the Lord is celebrated on the Monday immediately following the Epiphany. Ordinary Time continues until Ash Wednesday (violet), which marks the beginning of the Season of Lent (violet). Thus for Roman Catholics the period of Ordinary Time between Christmas and Lent may last from four to nine weeks, depending upon the dates of Epiphany (American Catholics) and Ash Wednesday. Ash Wednesday is a moveable feast based on the date of Easter (white). In the Church of England the first period of Ordinary Time is somewhat shorter — indeed it may be as short as a single day if Ash Wednesday falls on its earliest possible date of February 4.
