#primstav
If you do it right, you can have four Yules:
Dec 21: Common modern Yule dates starting on the winter solstice and usually ending Jan 1st.
Jan 12/14: Primstav date for Midwinter (Julian calendar). Using this, Yule would start here and go for three nights. Some debate on exact date.
Jan 19: Primstav Midwinter converted to the Gregorian calendar. Still three nights.
Jan 16 (2022): Old Norse lunisolar dates for Yule. Held for three nights during the full moon following the new moon after the solstice. In 2022 this is Jan 17 at its peak and includes the two surrounding dates. Consequently, the dates move around between Jan 5 and Feb 2.
You can certainly pick one to go with, or even just wrap them all into Yuletide.
This is the third full moon after the Yule Moon, and that means that by both Primstav and Old Norse lunar reckoning the summer season and the month of Harpa have begun!
