The Longest Day

The Summer Solstice in the Northern Hemisphere

In the Northern Hemisphere the summer solstice, the longest day of the year, occurs around June 21st. The opposite day, the shortest of the year, is the Winter Solstice , which occurs around 21 December each year.

In the Southern Hemisphere the respective dates are reversed, Winter Solstice occurs on the same day in June and Summer Solstice same day in December.

There are also two days in the year when the day and night are of equal duration. These are known as the Equinox days.

In the Northern Hemisphere the Vernal Equinox (Spring Equinox) occurs around March 21st whilst the Autumnal Equinox (Fall Equinox) occurs around September 21st each year.

Again in the Southern Hemisphere the respective dates are reversed.

Solstice and Stonehenge

Anna Monks

The word solstice comes from the Latin for midsummer expressing the idea that the sun is stopped in its ascent of the sky.

The earth's tilt means that the sun's position varies by 46° during the yearly orbit. The northerly limit is known as the Tropic of Cancer and the southerly limit is the Tropic of Capricorn.

At about 21st June the sun is directly over the Tropic of Cancer providing the northern hemisphere with its longest day. In December the southern hemisphere enjoys its summer solstice when the sun is directly above the Tropic of Capricorn.

Human habitation reaches higher latitudes in the northern hemisphere. People cannot sleep during the midsummer nights when it does not get completely dark.
Many Scandinavian communities have feasts, folk music and dance. Some festivals are held on the solstice and others on the Feast of St John. In Britain St John's day is called Midsummer's day.

The association of magic with midsummer in English culture is exemplified by Shakespeare's delightful comedy "A Midsummer Night's Dream". In the play normality is turned upside-down and fairies interfere with human affairs.
The woodland setting becomes an enchanted place with supernatural rulers.

There is strong evidence that celebration of the summer solstice goes back to the Neolithic period as so many monuments seem to align with the summer sunrise.
In England the great circle known as Stonehenge has an alignment of stones marking sunrise on the longest day. Sadly, we have no idea how the henge was used, but we can be sure that its builders were astronomers.
