After decades of head-scratching, researchers finally cracked the Maya calendar’s 819-day cycle. Turns out, it’s not just a random number—it actually syncs up with the movements of all the visible planets! By stretching the count over 45 years, every planet’s cycle fits perfectly. The Maya were basically the OG cosmic schedulers, weaving together ritual, politics, and astronomy in one mind-blowing system. Ancient skywatchers were on another level! #Science #MayaCalendar #HistoryMystery
