It had lengthy been thought that the well-known website of Stonehenge served as an historical calendar, given its alignment with the solstices. Now, analysis has recognized the way it could have labored.
New finds in regards to the stone circle’s historical past, together with evaluation of different historical calendar methods, prompted professor Timothy Darvill to take a recent take a look at Stonehenge. His evaluation, revealed within the journal Antiquity, concluded that the location was designed as a photo voltaic calendar.
“The clear solstitial alignment of Stonehenge has prompted folks to counsel that the location included some form of calendar because the antiquarian William Stukeley,” mentioned Darvill, from Bournemouth University, “Now, discoveries introduced the problem into sharper focus and point out the location was a calendar primarily based on a tropical photo voltaic 12 months of 365.25 days.”
Crucially, latest analysis had proven that Stonehenge’s sarsens had been added throughout the identical section of development round 2500 BC. They had been sourced from the identical space and subsequently remained in the identical formation. This signifies they labored as a single unit.
As such, Darvill analyzed these stones, analyzing their numerology and evaluating them to different identified calendars from this era. He recognized a photo voltaic calendar of their format, suggesting they served as a bodily illustration of the 12 months that helped the traditional inhabitants of Wiltshire hold monitor of the times, weeks, and months.

“The proposed calendar works in a really easy approach. Each of the 30 stones within the sarsen circle represents a day inside a month, itself divided into three weeks every of 10 days,” mentioned Darvill, noting that particular stones within the circle mark the beginning of every week.
Additionally, an intercalary month of 5 days and a leap day each 4 years had been wanted to match the photo voltaic 12 months. “The intercalary month, most likely devoted to the deities of the location, is represented by the 5 trilithons within the middle of the location,” mentioned Darvill. “The 4 Station Stones exterior the Sarsen Circle present markers to notch-up till a leap day.”
As such, the winter and summer season solstices can be framed by the identical pairs of stones yearly. One of the trilithons additionally frames the winter solstice, indicating it could have been the brand new 12 months. This solstitial alignment additionally helps calibrate the calendar—any errors in counting the times can be simply detectable because the solar can be within the fallacious place on the solstices.
Such a calendar, with 10 day weeks and additional months, could seem uncommon at this time. However, calendars like this had been adopted by many cultures throughout this era

“Such a photo voltaic calendar was developed within the jap Mediterranean within the centuries after 3000 BC and was adopted in Egypt because the Civil Calendar round 2700 and was broadly used initially of the Old Kingdom about 2600 BC,” mentioned Darvill. This raises the chance that the calendar tracked by Stonehenge could stem from the affect of one among these different cultures. Nearby finds trace at such cultural connections—the close by Amesbury archer, buried close by across the identical interval, was born within the Alps and moved to Britain as an adolescent.
Professor Darvill hopes future analysis would possibly make clear these potentialities. Ancient DNA and archaeological artifacts may reveal connections between these cultures. Nevertheless, the identification of a photo voltaic calendar at Stonehenge ought to remodel how we see it.
“Finding a photo voltaic calendar represented within the structure of Stonehenge opens up an entire new approach of seeing the monument as a spot for the dwelling,” he mentioned, “a spot the place the timing of ceremonies and festivals was related to the very material of the universe and celestial actions within the heavens.”
