King used to enthrone his heir in his life. After father’s death, son ruled alone. Which was starting point for his regnal years, the one when he joined father on the throne, or the one when he was left alone on the throne. It is well recorded that David VI, Vakhtang II and Giorgi V (the kings of Georgia in the 13th -14th cc.) thought about their first year of co-regnancy as of first year of their general rule. That was a tradition in the 11th -14th cc. to count the regnal years from co-regnancy. Only few exceptions took place.geბაგრატიონებიქართველი მეფეებიზეობარეგენტიArticle
