Calendar Theory


Although Stonehenge is surrounded by mystery and clouded in the mists of time one certain use of the ancient monument is to mark the summer and winter solstices. This theory is linked with some of the other theories as the druids celebrate on the summer solstice of which Stonehenge shows.

The stones are aligned in such a way as to provide sight lines for the sun and the moon on certain dates. Stonehenge marks the summmer and winter solstices which are the longest and shortest days of the year. Even though that is quite important and advanced back 5,000 years ago that's all it does. Another thing about Stonehenge is that it is linked to the Sequani calendar which is an ancient bronze tablet discovered in Coligny,France in 1897. It is the calendar of a tribe of people called the Celts. Information from professors around the world tell us that both Stonehenge and the Sequani calendar are luni-solar. If Stonehenge and the Sequani calendar are luni-solar it means that they are both based on a 19 year cycle (metonic cycle) of the moon. They both have months alternating from 29 to 30 nights and can both be expanded into 235 months that are divided into light and dark halves which begin at the first quarter moon. The months have the full moon marked on the eighth night on the light half of each lunar cycle and the new moon on the eighth night on the dark half of each lunar cycle. The fact that the link between the Sequani calendar and the mysterious Stonehenge exists makes this theory a well backed up one with lots of evidence so this could be what Stonehenge was used for.
