The eighth month of the Celtic year is the second month of the Celtic winter. Etymology suggests it is derived from the proto-Indo-European *sem-, 'to flow' and -uis- 'water', thus 'water flowing' as a reference to the mid-point of the solar cycle, the winter solstice. The second component of the word -uis- may share an origin with the 'navel of Ireland', Uisnech. A concept of origin in flowing out in the name Semiuisonna stands as complementary to the summer solstice month, Duman, whose name has a meaning of 'all-encompassing'. Across Europe since the Bronze age the observance of the two solstices was recorded, most famously in the megalithic monuments with solar alignments. These significant points in the annual progression of the year remain celebrated in the Celtic calendar, despite its Beltaine/Samhain alignment which was of paramount importance in the arable and pastoral communities of the Iron Age. The adoption of the cult of Mithras by Rome in AD274 by Aurelian saw formal celebration of the Unconquered Sun's nativity on December 25 the date then associated with the solstice. This was transferred to the nativity of Christ in AD354 and remained associated with the solsticial beginning of the year. The solstices are marked on many neo-pagan calendars as part of an eight-fold progression of the year. As seen with the equinoxes, so too are the solstices commemorated in their respective lunations in the Celtic calendar, but the only cardinal points are the start of Summer and Winter. The Source, that which flows, is the River, whether she be the River of Danu, the Danube in the Celtic homeland, or the River of Sequana, the Seine, the River of Sabrann, the Severn, or the Rivers of Boann or Siann, the Boyne an the Shannon. Like the Well of Wisdom with its hazels at the source of the Boyne, the font of Celtic origins lays at the source of the rivers of Danu.

In 503BC, the planet Saturn appeared in Taurus marking the start of a Celtic 30 year cycle as described by Plutarch.
Caer Australis presents the hypothesis that this was the first 'Celtic Calendar Year', at the dawn of the La Tène Period.
Shown above (using Cybersky) is the European dawn of December 503BC, Semiuisonna, around the winter solstice.
This month in the Southern Hemisphere
In Australia and the Southern Lands the seasons are offset by half a year and so the month of Semiuisonna contains the summer solstice. As in the Gregorian Calendar, in the Southern Hemisphere all month names retain their Northern attributes. The lunation of Southern Semiuisonna may be named 'the Duman moon' to express the seasonality of the Celtic calendar. The Southern Celtic Year 2007 explores the southern hemisphere perspective.
