The longest day of the year.

The longest day of the year.

The longest day of the year 2014 is going to be 21st of June. How is this established, what is the summer solstice and the winter solstice and how are these dates calculated are some of the things you can find in the following post about the longest and shortest days of the year. Enjoy!

What is the solstice?

A solstice is an astronomical event that marks the moment in which the Sun reaches its highest or lowest excursion relative to equator. This happens twice a year in each of the hemispheres. The day of the solstice is either the longest day of the year, in summer or the shortest day of the year, in winter for any place outside of the tropics. So the days are longer around the summer solstice and shorter around the winter solstice. The fact that the Sun is higher in the sky during the day and its rays hit the ground at a more direct angle, causes the warming we feel during summer.

The word solstice derives from the Latin “solstitium” meaning sol (sun) and stitium (to stop), because the sun appears to stop at the time of the solstice.

For the Northern Hemisphere the sun reaches the highest position in the sky in June (the Summer solstice) and the lowest position in December (the Winter solstice). In the Southern Hemisphere things are reversed as the longest day of the year marked by the Summer solstice occurs in December and the shortest day, marked by the Winter solstice occurs in June.

Another notion to take into consideration is another astronomical event called the equinox that also occurs twice a year. During an equinox the Sun’s path crosses the equator, therefore the length of the night is equal to the length of the day. The two equinoxes occur in March and September half way between the two solstices. The solstices, together with the equinoxes, are connected with the beginning of the seasons.

What is the Summer solstice?

The Summer solstice marks the moment when the sun reaches the highest position in the sky when the rays of the sun are perpendicular to the Tropic of Cancer at 23°30' North latitude. The summer solstice occurs when Earth's axis is the most tilted toward the sun -- the angle is known as "maximum axial tilt." This represents the day with the most hours of sunlight in the whole year. Most places in the US receive about 14-16 hours of daylight during the Summer Solstice. This is the beginning of the astronomical summer in the Northern Hemisphere and usually occurs around 21st of June.

The Summer solstice is also called midsummer and has long been recognized and often celebrated with holidays and festivals by many cultures around the world. These celebrations have been associated with religion and agriculture as the Summer solstice was a reminder of the growing season. On the day of the Summer solstice in the Northern Hemisphere the Sun appears to have reached the highest annual altitude in the sky at local solar noon.

When is the longest day of the year 2014?

The longest day of the year is also called the Summer solstice. This year's summer solstice falls on Saturday, June 21 2014 at 10:51 UTC so this means that June 21 is the longest day of 2014. In the Northern Hemisphere the winter solstice that marks the shortest day of 2014 occurs on December 21. In the Southern Hemisphere the dates are reversed.

The timing of the solstice depends on when the Sun reaches its farthest point north of the equator and this varies from year to year. Precise dates and times of solstices and equinoxes for the next years are listed in the table below:

    Our ability to tap into the collective consciousness is still within us. We’ve just forgotten how to use it. I use numerology, which has completely surprised me and changed my life for good.

    The reason why fortune telling became associated with the observance of the sun moon and stars was simply the need to know when to plant and how to avoid frost. From this the idea of predicting the future solstice or Equinox became strategic information for tides and war. When to wage war was "tide" to the full moon and clear skies. Observation lead to calculation which lead to prediction and that to superstitious reasoning by the uneducated. The Church then enshrined the old ways as commandments,, judgements and deviation from dogma was deemed "lunacy." Later after calculation supplanted observation the lunatics were the ones who kept vigil over the full and new moons. So observation of dates and times became religious points of view such that "the hand of god" does not permit change or new discovery. As well as "god does not play dice with the universe..." The association of observation with the naked eye and the nature of all things left the church having t make up for changing times, recanting the charges of heresy only after new data was accepted by even the most uneducated of us. I read a lot of "mythology" and this is my finger nail conclusion.
