The holidays

[Britney]

A period of roughly six weeks, lasting from the end of November to some time in January. It includes a number of religious holidays, traditional celebrations, and family visits. It is generally accepted to be both the best part of the year (for people under the age of fifteen) and the worst part of the year (for people over the age of fifteen).
Includes: Thanksgiving, Hannukah, Advent, Christmas Eve, Christmas Day, the [Winter Solstice], [St. Nicks] Day, Kwanzaa, Boxing Day, New Years Eve, New Years Day, Winter Break (for students), and a number of others.
Sometimes used (as Happy Holidays) as a politically correct (race, creed, and nationality-neutral) phrase on cards and decorations.
Also known as International [Muzak] Month due to the unwavering propensity of shopping establishments to assault their customers ears with instrumental version of Do You Hear What I Hear, Jingle Bell Rock, and [White Christmas] for the entire six-week period.
