In the Western Christian calendar, Ash Wednesday is the first day of Lent and it occurs forty days before Easter (excluding Sundays). It falls on a different date each year, and 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 palms 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 clergyman 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 that you are dust, and to dust you shall return."
Not all Christian churches observe Ash Wednesday or Lent. The Bible does not mention Ash Wednesday or the custom of Lent, however, the practice of repentance and mourning in ashes is found in 2 Samuel 13:19; Esther 4:1; Job 2:8; Daniel 9:3; and Matthew 11:21.
Ash Wednesday follows Fat Tuesday, the last day of the carnival season, so called because believers used all the fat left over in their kitchens to prepare rich foods before the traditional fasting of Lent. Since the earliest times of the Church, there is evidence of some kind of Lenten preparation for Easter.
Lent becomes more regularized after the legalization of Christianity in A.D. 313. The Council of Nicea (325), in its disciplinary canons, noted that two provincial synods should be held each year, "one before the 40 days of Lent." St. Athanasius (d. 373) in this "Festal Letters" implored his congregation to make a 40-day fast prior to the more intense fasting of Holy Week. St. Cyril of Jerusalem (d. 386) in his Catechectical Lectures, which are the paradigm for our current RCIA programs, had 18 pre-baptismal instructions given to the catechumens during Lent.
St. Cyril of Alexandria (d. 444) in his series of "Festal Letters" also noted the practices and duration of Lent, emphasizing the 40-day period of fasting. Finally, Pope St. Leo (d. 461) preached that the faithful must "fulfill with their fasts the Apostolic institution of the 40 days," again noting the apostolic origins of Lent. One can safely conclude that by the end of the fourth century, the 40-day period of Easter preparation known as Lent existed, and that prayer and fasting constituted its primary spiritual exercises.Once the 40 days of Lent were established, the next development concerned how much fasting was to be done. In Jerusalem, for instance, people fasted for 40 days, Monday through Friday, but not on Saturday or Sunday, thereby making Lent last for eight weeks. In Rome and in the West, people fasted for six weeks, Monday through Saturday, thereby making Lent last for six weeks. Eventually, the practice prevailed of fasting for six days a week over the course of six weeks, and Ash Wednesday was instituted to bring the number of fast days before Easter to 40. The rules of fasting varied. First, some areas of the Church abstained from all forms of meat and animal products, while others made exceptions for food like fish. For example, Pope St. Gregory (d. 604), writing to St. Augustine of Canterbury, issued the following rule: "We abstain from flesh, meat, and from all things that come from flesh, as milk, cheese and eggs."
Second, the general rule was for a person to have one meal a day, in the evening or at 3 p.m. These Lenten fasting rules also evolved. Eventually, a smaller repast was allowed during the day to keep up one's strength from manual labor. Eating fish was allowed, and later eating meat was also allowed through the week except on Ash Wednesday and Friday. Dispensations were given for eating dairy products if a pious work was performed, and eventually this rule was relaxed totally. (However, the abstinence from even dairy products led to the practice of blessing Easter eggs and eating pancakes on Shrove Tuesday, the day before Ash Wednesday.)Over the years, modifications have been made to the Lenten observances, making our practices not only simple but also easy. Ash Wednesday still marks the beginning of Lent, which lasts for 40 days, not including Sundays.
The present fasting and abstinence laws are very simple: On Ash Wednesday and Good Friday, the faithful fast (having only one full meal a day and smaller snacks to keep up one's strength) and abstain from meat; on the other Fridays of Lent, the faithful abstain from meat. People are still encouraged "to give up something" for Lent as a sacrifice. (An interesting note is that technically on Sundays and solemnities like St. Joseph's Day (March 19) and the Annunciation (March 25), one is exempt and can partake of whatever has been offered up for Lent.
