The summer solstice is the period when the Sun reaches the northermost point of its imaginary path, i.e. the tropic of Cancer; then the period of sunlight is the longest. People have always worshipped the Sun; the ancient celebrations have roots in prehistory and are celebrated in the whole world regardless its culture. When the Sun in its orbit reaches the closest distance to the Earth marks the beginning of astronomical summer. Day Five is thereby dedicated both to astronomy and astrology.
