Deeside residents can now say time began in the area after the discovery of the “world’s oldest calendar” in Crathes.
Archeologists have found a 10,000 year old set of 12 pits at Warren Field.
The pits are believed to represent the 12 months.
The discovery has given scientists a new understanding of how Stone Age humans measured the passage of time.
A 5000-year-old “calendar” from Bronze age Mesopotamia is the site’s nearest known rival.
Scottish National Trust archeologists first began excavating the site in 2004.
A team from the University of Birmingham have since analysed the findings and suggest the ancient monument was created by hunter-gatherers around 8000 BC.
The analysis has been published in the journal, Internet Archaeology.
The Warren Field site was first discovered as unusual crop marks spotted from the air by the Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS).
