than the several days leading up to and following it and although the actual Julian date of Winter solstice would have been on 15 or 14 December at the time when Christianity was introduced to Scandinavia, 13 December could well have lodged in people's mind as being the shortest day. The choice of 13 December as Saint Lucy's day, however, predates the eight-day error of the 14th century Julian calendar. This date is attested in the pre-Tridentic Monastic calendar, probably going back to the earliest attestations of her life in the sixth and seventh centuries, and it is the date used throughout Europe. So, while the world changed from a Julian to a Gregorian calendar system—and hence acquired a new date for the Winter Solstice—St Lucy's Day was kept at 13 December, and not moved to the 21. In the Roman Empire, 25 December (in the Julian Calendar) date was celebrated as being the day when the Sun was born, the birthday of Sol Invictus, as can be seen in the Chronography of 354. This date corresponding to the Winter solstice. Early Christians considered this a likely date for their saviour's nativity, as it was commonly held that the world was created on Spring equinox (thought to fall on 25 March at the time), and that Christ had been conceived on that date, being born nine months later on Winter solstice. A Swedish source states that the date of (Winter Solstice, St. Lucia, Lucinatta, Lucia-day, Lussi-mass...) i.e. 13 December, predates the Gregorian which implies that "Lucia's Day" was 13 Dec in the Julian Calendar, which is equal to 21 December in the Gregorian, i.e. now. Same source states use of the name "Little Yule" for the day, that it was among the most important days of the year, that it marked the start of Christmas month, and that with the move to the Gregorian calendar (in Sweden 1753) the date (not the celebration) "completely lost its appropriateness/significance". Saint Lucy According to the traditional story, Lucy was born of rich and noble parents about the year 283. Her father was of Roman origin, but died when she was five years old, leaving Lucy and her mother without a protective guardian. Although no sources for her life-story exist other than in hagiographies, St. Lucy, whose name Lucia refers to "light" (Lux, lucis), is known to have been a Sicilian saint who suffered
