These days, it's common practice to wish "Merry Christmas" to one another around the 25th of December, the day of Christmas. The origin of this practice is a little obscure. However, it's believed that an English admiral first used the term Merry Christmas in an informal letter, way back in 1699. In 1843, Charles Dickens used the same phrase in "A Christmas Carol." However, notwithstanding the veracity of its origin, "Merry Christmas" has become a sort of universal term to communicate joy and good wishes.
