What happens on Ash Wednesday today?

Many Christians will attend a religious service where the ashes are blessed by the church leader, and placed on their forehead.
Christians believe this marks the physical and spiritual beginning of a personal Lent season in which 40 days of repentance will begin leading up to the celebration of Easter Sunday.
The actual moment when the forehead is marked initiates the beginning of lent for each individual person. May we all fine solace and peace with our hearts.
