9. Christmas Christmas, also referred to as Christmas Day or Christmastide, is an annual holiday celebrated on December 25 that marks and honours the birth of Jesus of Nazareth. His birth, which is the basis for the Anno Domini system of dating, has been determined by modern historians as having occurred between 7 and 2 BC. The date of celebration is not thought to be Jesus' actual date of birth, and may have been chosen to coincide with ancient Roman solar festivals that were held on December 25.

10. Saints’ Calendar The Calendar of saints is a traditional Christian method of organizing a liturgical year on the level of days by associating each day with one or more saints, and referring to the day as that saint's feast day. The system arose from the very early Christian custom of annual commemoration of martyrs on the dates of their deaths, or birth into heaven (and thus referred to in Latin as dies natalis, "day of birth"). As the number of recognized saints increased during Late Antiquity and roughly the first half of the Middle Ages, eventually every day of the year had at least one saint who was commemorated on that date. Eventually, some saints were moved to another day in some traditions, or completely removed; thus, some saints do have more than one day. The General Roman Calendar in its various forms contains only a selection of the saints of each day.
