A Brief History of the Calendar Today we take the precision of our calendar for granted, seldom considering the remarkable journey that made it possible. Yet the calendar we use every day is the result of more than 5,000 years of observation, mathematics, astronomy and human ingenuity. From the earliest attempts to track the Sun, Moon and seasons to the sophisticated systems that keep our clocks aligned with the motions of the celestial sphere, the story of the calendar is one of continual refinement and discovery. Join GRASSA for an engaging presentation that explores this fascinating history, highlighting the challenges our ancestors faced and the astronomical principles that continue to shape the way we measure time. GRASSA Monthly Meeting Saturday, 15h00 Environmental Centre, George Botanical Gardens Free entrance for all via the Aloe Gate from 14h30 to 15h00. Everyone is welcome to attend.
