Hosted by Erica M.: PhD in ANCIENT SCIENCES and Babylonian ASTRONOMY.
This year may not have a February 29, but this mysterious date often causes calendrical confusion! Leap years have a long history, and cultures across the ancient world have found ways of accounting for these wandering extra days, ranging from extra short weeks at the end of the year to full extra months every so often. In this virtual tour, you will:
– Gain an understanding of what leap years are and why they happen
– See the astronomical events lying behind the concept of “leap” years using at-home planetarium software
– Hear about calendar systems from ancient cultures across the globe
– Learn how leap years appear throughout history
We believe knowledge must be FREE, available to everyone. Just get your Free pass and ENJOY!

Hi, I'm Erica Meszaros, and I earned my PhD in the History of the Exact Sciences in Antiquity from Brown University in 2025. My research centers on Babylonian astronomy and knowledge circulation in the ancient world, using algorithms to interpret these fascinating cultures. I've interned at four NASA centers, fueling my passion for space. I read Akkadian, Sanskrit, Ancient Greek, and Latin and love exploring ancient "pre-scientific" mathematics and science. Sharing these insights is my greatest joy!
