Holiday greetings[edit]

Main article: Holiday greetings
It is increasingly common for Americans to say "Happy holidays", referring to all, or at least multiple, winter (in the Northern hemisphere) or summer (in the Southern hemisphere) holidays (Christmas, Hanukkah, Kwanzaa, etc.) especially when one's religious observances are not known; the phrase is rarely heard in the UK. In the UK, the phrases "holiday season" and "holiday period" refer to the period in the summer when most people take time off from work, and travel; AmE does not use holiday in this sense, instead using vacation for recreational excursions.
In AmE, the prevailing Christmas greeting is "Merry Christmas", which is the traditional English Christmas greeting, as found in the English Christmas carol "We Wish You a Merry Christmas", and which appears several times in Charles Dickens' A Christmas Carol.^[17] In BrE, "Happy Christmas" is a common alternative to "Merry Christmas".
