June 21st, 2014 marks the beginning of the Summer Solstice, when the Earth’s axis is most inclined toward the Sun in the Northern Hemisphere. The first day of the Summer Solstice also marks the longest period of daylight in the year. The summer solstice is often a time of celebration around the northern hemisphere for various reasons. One is the official beginning of summer–warm temperatures, the beach, and vacation. The other is for various cultural celebrations tied to the astronomical event.
