Summarize the following:
Palm Sunday is exactly one week before Easter. Palm Sunday celebrates Christ's entry into Jerusalem. It also marks the beginning of Holy Week. The entire week is often referred to as “Holy Week,” but the Thursday, Friday, and Saturday immediately before Easter in particular are recognized as dates of significance in the Christian calendar.  Maundy Thursday celebrates the Last Supper of Christ. It also recognizes the "washing of feet," a biblical event during which Jesus washed the feet of his Apostles. Many Christian denominations celebrate the maundy (washing of feet) as a church ordinance. Good Friday recognizes the day that Christ was crucified. Holy Saturday commemorates the time during which Christ's body lay in the tomb. It is typically viewed as a day of preparation for Easter Sunday. Trace back to the Sunday that came six calendar weeks earlier. The Wednesday immediately before that date is Ash Wednesday.  In other words, Ash Wednesday is 46 days before Easter each year. Ash Wednesday is a formal day of repentance in many Christian churches. It also marks the first day of Lent, a period of 40 days over which Christians are to spiritually prepare for Easter. Ascension Day is a Christian holiday that falls exactly 39 days after Easter Sunday. Ascension Day celebrates Christ's ascension into heaven. In some Christian denominations, it is also considered the “fortieth day of Easter,” meaning that all the days in between Easter Sunday and Ascension Day are part of the broader Easter season.
Back up one week to find Palm Sunday. Pay special attention to the week in between Palm Sunday and Easter. Count back to the Wednesday six weeks before Easter. Count 40 days ahead.
