It's Ash Wednesday, a holy day that marks the first day of Lent for Christians around the world.
Parishioners at St. Mary Cathedral in Lansing will receive the sign of the cross in ashes on their foreheads.
Mass is set for 8:00 a.m., 12:05 p.m., and a third one late this afternoon at 5:15 p.m.
Lent is forty days long, and people use the time to pray, fast, or give up something in preparation for the Easter holiday.
