Celtic calendar
From Free net encyclopedia
The term Celtic calendar is used to refer to a variety of calendars used by Celtic-speaking peoples at different times in history.

Neolithic Calendar?
A neolithic engraved stone found at Knowth, Ireland, may be a graphical representation of a lunar calendar. While pre-dating the Celts, Brennan (1994) speculates that it operates on the same principle as the Coligny calendar.
Continental Celtic Calendar
Possibly the oldest material Celtic calendar is the fragmented Coligny calendar, which was discovered in Coligny, France, in 1897. It uses Roman numerals and dates to the 1st century, BC or AD, a time when the Roman Empire imposed use of the Julian Calendar in Roman Gaul.
The Coligny calendar was lunisolar- a way to reconcile lunations and the solar year. The astronomical format of the calendar year that the Coligny calendar represents, may well be far older, as calendars are usually even more conservative than rites and cults. The date of its inception is unknown, but correspondences of Insular Celtic and Continental Celtic calendars suggest that some early form may date to Proto-Celtic times, roughly 800 BC.
The Coligny calendar registers a five-year cycle of 62 lunar months, divided in a "bright" and a "dark" half-moon or fortnight each. The months were taken to begin at full moon, and a 13th intercalary month was added every two and a half years to align the lunations with the solar year.
The Coligny calendar is now in the Gallo-Roman museum of Lyon.
Mediaeval Irish and Welsh Calendars
The first part of the year started at Samhain, which was the first of November, never far from what would become Halloween and the following All Saints Day in our modern solar calendar. The second part of the year started at Beltaine which was around the first of May.
Celtic days began at sundown: "they keep birthdays and the beginnings of months and years in such an order that the day follows the night," their adversary Julius Caesar observed Gallic Wars. Longer periods were reckoned in nights, as in the surviving term "fortnight."
Neo-Pagan calendars
In some Neo-Pagan religions, a Celtic calendar based on that of Mediaeval Ireland is observed for purposes of ritual. This does not necessarily indicate that a Celtic language is used for ritual. In other cases, the four Irish festivals of Samhain, Imbolc, Beltane and Lughnassadh are combined with the solstices and equinoxes to produce the modern Neo-Pagan Wheel of the Year. Syncretistic Neopagans are sometimes also influenced by Robert Graves' "Celtic Astrology", which has no foundation in historical calendars.
