The Antikythera Mechanism contains, among its many features, a movable calendar ring with three Egyptian month names engraved in ancient Greek.1 The calendar ring has been universally supposed, without validation, to be an unremarkable example of what is generally referred to as the ‘Egyptian civil calendar’ — a non-lunar calendar of precisely 365-day duration, comprised of twelve 30-day months, plus five epagomenal or ‘intercalary’ days.In this article we reconsider this feature, and provide new data to show this interpretation to be incorrect, and displace the century-long assumption of a 365-day calendar on the Antikythera Mechanism, proposing instead that it is a 354-day lunar calendar.
