The penitential season of Lent begins with Ash Wednesday, designated the first of two fast days (the other being Good Friday), and extends to Easter Eve. The collect for Ash Wednesday is one of the ancient prayers of the Church. It can be traced to the 8th century. It is inspired by Psalm 51. When Archbishop Cranmer crafted the first Prayer Book, he included the collect and made some adjustments to it. In times past, the collect was used daily in Lent.
