↑ Not all Catholics observe Ash Wednesday. Công giáo Đông phương, who do not count Tuần Thánh as part of Lent, begin the penitential season on Clean Monday, the Monday before Ash Wednesday, and Catholics who follow the Ambrosian Rite begin it on the First Sunday in Lent. Ashes are blessed and ceremonially distributed at the start of Lent throughout the Giáo hội Latinh and in the Giáo hội Maronite and the Syro-Malabar Catholic Church. In the Ambrosian Rite, this is done at the end of the Sunday Mass or on the following day.[1][2]
