For most Christians, the most important holiday is probably Easter Sunday, which commemorates the resurrection of Christ from the tomb. This event is especially important to Christians because it is treated as proof of Christ's divinity. Traditionally, individuals attend church services on Easter, and often celebrate with a meal that includes lamb and other traditional foods, depending on the culture.

Chronologically, the first of the major holidays is Epiphany, which occurs on the sixth of January. This holiday celebrates the three "Wise Men" who attended the birth of Christ with gifts. The next major holiday is Ash Wednesday, which occurs 40 days before Easter, commemorating the start of Lent. During Lent, some Christians observe special dietary rules, and many devout people give something up for Lent, using these 40 days as a period of reflection and religious contemplation.

As Lent draws to a close, some Christians celebrate Holy Week, which commemorates the entrance of Christ into Jerusalem on Palm Sunday, through His crucifixion on Good Friday. Holy Week ends with Easter Sunday, the most important of Christian holidays discussed above. The next big holiday is Pentecost, celebrated on the seventh Sunday after Easter, when the Holy Spirit is said to have descended upon the disciples of Christ.

Many Christians around the world also celebrate Christmas, the commemoration of Christ's birth, on 25 December each year. Some also observe Advent in the weeks leading up to Christmas, attending special church services during this period. Christmas celebrations can get quite elaborate, making it one of the more well-known holidays, as people exchange gifts, attend parties, and celebrate the birth of Christ.
