Another thing, but this is optional...I looked the script, the year 360 has only 6 turns, and every year has 6 summer turns followed by 6 winter turns...it would be fine to make 3winter (jan, feb, march) +6summer (apr,may,jun,jul,aug,sept) +3winter (oct,nov,dec). So, you always have 6 winter followed by 6 summer, but the start of the year changes...
