The Papa Stronsay Calendar is out now to order, and it can be purchased at the bottom of this post. In the promotional video, also found below, the sun's course through the constellations of the Zodiac is mentioned as being marked on the calendar. The Zodiac is these days associated almost entirely with superstitious astrology, but the Zodiac is not astrology.
Timekeeping was devised by identifying and measuring the movement of the Sun and Moon across the Zodiac constellations. A 360 degree system plots and times the course of the Sun in a year. The coordinate system can be easily divided by 60, 30 and 15. A minute has 60 seconds. An hour 60 minutes. One day of 24 hours divided by 2 is 12. The stars move towards the west one minute in distance, every minute, or one degree every four minutes. The sun and stars move fifteen degrees in one hour. Fifteen degrees multiplied by the four which it takes to complete one degree gives us sixty minutes. Thus the very time which we daily read from our wrist-watch is determined by tracking the motion of the sun and stars across the sky.
More to come, so watch this space!
