"Merry," derived from the Old English myrige, originally meant merely "pleasant" rather than joyous or jolly (as in the phrase "merry month of May").
Though Christmas has been celebrated since the 4th century AD, the first known usage of any Christmastime greeting, "Merry Christmas and a Happy New Year" (thus incorporating two greetings) was in an informal letter written by an English admiral in 1699. The same phrase appeared in the first Christmas card, produced in England in 1843. (Yahoo).
Oak Valley College wishes you, and your family a great Christmas season. Enjoy the holidays. Lord willing, we will be celebrating the conclusion of our first semester this time next year.
Blessings from Oak Valley College.
