According to our dear friend, Wikipedia, Ash Wednesday can be summed up as the following.
In the Western Christian Calendar, Ash Wednesday is the first day of Lent and occurs forty-six days (forty days not counting Sundays) before Easter. It falls on a different date each year, because it is dependent on the date of Easter; it can occur as early as February 4 or as late as March 10.
Ash Wednesday gets its name from the practice of placing ashes on the foreheads of the faithful as a sign of repentance. The ashes used are gathered after the Palm Crosses from the previous year's Palm Sunday are burned. In the liturgical practice of some churches, the ashes are mixed with the Oil of the Catechumens  (one of the sacred oils used to anoint those about to be baptized), though some churches use ordinary oil. This paste is used by the priest who presides at the service to make the sign of the cross first upon his own forehead and then on each of those present who kneel before him at the altar rail. As he does so, he recites the words: "Remember (O man) that you are dust, and to dust you shall return."
I am not Catholic. However, I think that this is a good tradition to keep. My youth minister used to remind me that I was Baptist and that I didn't practice/believe in it. But my theory is that for these 40 days I can give something up for Christ's sacrifice for me. I realize that I can do it at any time, but my thought is to do so with other people. We all need a little support and strength is in numbers.
This year I'll be giving up...wouldn't you like to know?
