The summer solstice occurs exactly when the Earth's semi-axis in a given hemisphere is most inclined towards the sun, at its maximum tilt of 23° 26' and the day on which the summer solstice occurs is the day of the year with the longest period of daylight. The summer solstice occurs in June in the Northern Hemisphere north of the Tropic of Cancer (23°26'N) and in December in the Southern Hemisphere south of the Tropic of Capricorn (23°26'S).
Worldwide, interpretation of the event has varied among cultures, but most have held a recognition of sign of the fertility, involving holidays, festivals, gatherings, rituals or other celebrations around that time. The word solstice derives from Latin sol (sun) and sistere (to stand still).
Metaphysically, the summer solstice (also known as Litha) is a time of intensity, renewal and great potential. This is symbolic of the light of our consciousness shining more brightly in our awareness. It's also symbolic passion, desire and sensuality burning more intensely within the hearts of both humankind and animal kind.
