The Secrets of the World’s Oldest Calendar Revealed: The Mesolithic Hunter-Gatherer Time Keepers

If I was to ask you where the oldest calendar in the world was found, where would you say? Some may say somewhere exotic like ancient Babylon or ancient Egypt; others might say don’t know, don’t care – if that that’s you, I’ll see you later; how many would say Scotland however?

Today, I’ve come Warren Field in Aberdeenshire, the site of the oldest calendar in the world. Dating back 10,000 years ago to around 8,000 BC, this Mesolithic monument predates what was previously thought to have been the world’s oldest calendar by around 5,000 years, which was found in Mesopotamia.

The calendar is a series of 12 pits in the shape of a general arc that mimic the phases of the Moon and track the lunar months. There are also three smaller, undated, postholes adjacent to the central, and largest pit (pit number 5). This lunar calendar was also aligned with the Midwinter Sunrise, which worked to calibrate the calendar. Without this calibration, the lunar calendar which inevitably fall out of sync with the seasons as a lunar calendar alone is not an accurate tracker of seasons without some correction

As Vince Gaffney, Professor of Landscape Archaeology at the University of Birmingham Gaffney and his colleagues write in Time and a Place: A luni-solar 'time-reckoner' from 8th millennium BC Scotland, published in the Internet Archaeology in 2013:
