No matter who we are or what we do, calendars play a major role in our lives. We organize, plan, celebrate and count down with the use of a calendar. And we’re not the first ones. Early on, the first people would measure time by observing the period of light and dark that alternated continuously. The earliest calendars were strongly influenced by the geographic location of the people who made them. Put Part 2 of this podcast into your calendar now, because Part 1 may just surprise you! Special thanks to our producer Jessica Crossman.
