Stonehenge may have been used as a solar calendar, with each of the stones representing a day and sections of the circle of stones possibly corresponding to weeks, an archaeologist now says.
An accurate solar calendar consists of about 365.25 days and is important for preventing the seasons from falling out of place (such as having winter during June). Meanwhile, the Gregorian calendar used in much of the world today consists of 365 days, with a leap day every four years to account for the quarter of a day.
Archaeologists have puzzled over the purpose of the 5,000-year-old monument and how it would have been used over time, with a range of ideas being proposed such as Stonehenge being a burial ground to it being used for religious ceremonies to it being used as a calendar.
