An advent calendar is a folk object typically used around Christmas time in between family members. It is a physical calendar with doors numbered 1 through 24, each representing a day up until Christmas Day. The subject used two different types of advent calendars. The first was a personal calendar that featured one chocolate a day. The second was a recurring wooden calendar featuring a house, significantly larger than the chocolate calendar. The doors were still labeled 1 through 24 but were not prefilled. Family members would get gifts for each other and place them in the days and the members would take turns opening the doors on the corresponding date of December.
The subject was taught this folk practice by their mother. Her mother would buy these advent calendars while they lived in Scotland together when the subject was younger. The subject remembers it because of the enjoyment she found when she was a little girl. She then introduced the tradition to her own family, and now they do it every year together. They think that it is a fun way to show appreciation and give smaller gifts to other family members. In addition, it gets everyone prepared for the Christmas season and keeps everyone in the holiday spirit, much like Christmas songs.
I think that folk practices such as the advent calendar are used to embody the intended spirit of Christmas more successfully. The idea of Christmas is to spend time with loved ones like friends and family and to give gifts and spread joy. In my opinion, acts like these are less about the gifts and more about the comradery and kindness, further spreading the sentiment of Christmas. It allows Christmas to be less of a build-up towards the monetary gifts one receives at the end, and more of a drawn-out feeling for people to share. Other similar things to this would be Christmas lights or carolers during the Christmas season. Although vastly different forms of folklore, both are about mood and time rather than one big buildup.
