The summer is right around the corner, but when exactly does the summer start? The first summer day in North America is Wednesday, June 21, 2023. The length of the astronomical seasons varies between 89 and 93 days, while the length of the meteorological seasons is less variable and is fixed at 90 days for winter in a non-leap year (91 days in a leap year), 92 days for spring, and summer, and 91 days for autumn.
You are probably planning to travel and go to different festivals. If so, you have a lot of time because the summer will last until Saturday, September 23, 2023.
June 21 will be the longest day of the year in the northern hemisphere, and the summer solstice.
Solstices and equinoxes mark the key stages in the astronomical cycle of the Earth and, as such, aren’t fixed. There are two equinoxes. Spring, autumn, and two solstices. Summer, and winter. The summer solstice often invites many superstitions, and traditional pagan ceremonies, including gatherings at Stonehenge.
I`m so fascinated by the Stonehenge. Who in the world built it? And how? Stonehenge is one of the most famous landmarks in the United Kingdom, and it`s regarded as a British cultural icon.
Archaeologists believe that Stonehenge was constructed from around 3000 BC to 2000BC., and the surrounding circular earth bank, and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC.
Radiocarbon dating suggests that the first bluestones were raised between 2400, and 2200 BC, although they may have been at the site as early as 3000 BC.
Stonehenge is a prehistoric monument on Salisbury Plain in Wiltshire, England, two miles west of Amesbury. It consists of an outer ring of vertical sarsen standing stones, each around 13 feet (4,0 m) high, seven feet (2,1 m) wide, and weighing around 25 tons, topped by connecting horizontal lintel stones.
25 tons? Who built it, and what tools did they use about 3000 years ago?
