Happy Solstice!

A solstice is an astronomical event that happens twice each year, when the tilt of the Earth's axis is most inclined toward or away from the Sun, causing the Sun's apparent position in the sky to reach its northernmost or southernmost extreme. The name is derived from the Latin sol (sun) and sistere (to stand still), because at the solstices, the Sun stands still in declination; that is, the apparent movement of the Sun's path north or south comes to a stop before reversing direction.

The term solstice can also be used in a broader sense, as the date (day) when this occurs. The solstices, together with the equinoxes, are connected with the seasons. In some cultures they are considered to start or separate the seasons, while in others they fall nearer the middle.

The Summer Solstice occurs exactly when the Earth's axial tilt is most inclined towards the sun at its maximum of 23° 26'. Though the Summer Solstice is an instant in time, the term is also colloquially used like Midsummer to refer to the day on which it occurs. Except in the Polar Regions (where daylight is continuous for half of the year), the day on which the Summer Solstice occurs is the day of the year with the longest period of daylight. Thus the seasonal significance of the Summer Solstice is in the reversal of the gradual shortening of nights and lengthening of days. The summer solstice occurs in June in the Northern Hemisphere, in December in the Southern Hemisphere.
June 20-21 is a very important day for our planet and its relationship with the sun. June 20-21 is one of two solstices, days when the rays of the sun directly strike one of the two tropical latitude lines. June 21 marks the beginning of summer in the northern hemisphere and simultaneously heralds the beginning of winter in the southern hemisphere. In 2010, the solstice occurs and summer begins in the Northern Hemisphere summer begins early on June 21, 11:28 UTC (16:58 Indian Standard Time).

The earth spins around its axis, an imaginary line going right through the planet between the north and south poles. The axis is tilted somewhat off the plane of the earth's revolution around the sun. The tilt of the axis is 23.5 degrees; thanks to this tilt, we enjoy the four seasons. For several months of the year, one half of the earth receives more direct rays of the sun than the other half.

When the axis tilts towards the sun, as it does between June and September, it is summer in the northern hemisphere but winter in the southern hemisphere. Alternatively, when the axis points away from the sun from December to March, the southern hemisphere enjoys the direct rays of the sun during their summer months.
June 21 is called the summer solstice in the Northern Hemisphere and simultaneously the winter solstice in the Southern Hemisphere. Around December 21 the solstices are reversed and winter begins in the northern hemisphere.

On June 21, there are 24 hours of daylight north of the Arctic Circle (66.5° north of the equator) and 24 hours of darkness south of the Antarctic Circle (66.5° south of the equator). The sun's rays are directly overhead along the Tropic of Cancer (the latitude line at 23.5° north, passing through Mexico, Saharan Africa, and India) on June 21.

Hundreds of years ago on the summer solstice, our ancestors sat in sun-drenched fields or on stones as warm as living flesh, fashioning small round suns from straw or vines, decorating them with sun-colored flowers, honoring the mysterious, fiery light that warmed and brightened their days and made the plants grow that fed them.

The summer solstice is a perfect time to help children make a tangible connection with the earth and to connect with the sun.

No matter where you live, Happy Solstice!
