Christmas and holiday greetings

Christmas and holiday greetings are a selection of greetings that are often spoken with good intentions to strangers, family, or friends, in nations around the world, during the Christmas and holiday season, spanning an approximate timeframe of late November through January. Holidays generally thought to be included in this season include Christmas, New Year's Day, Hanukkah, Boxing Day, Thanksgiving and Kwanzaa. Some greetings are more prevalent than others, depending on the cultural and religious status of any given area.
Typically, a greeting consists of the word "Happy" followed by the holiday, such as "Happy Hanukkah" or "Happy New Year", although the phrase "Merry Christmas" or "Seasons Greetings" can be a notable exception.
In the United States, the collective phrase "Happy Holidays" is often used as a generic cover-all greeting for all of the winter holidays: Thanksgiving, Christmas Day, New Year's Day, Hanukkah, and Kwanzaa; however, the phrase is not widespread in other countries.
