The summer solstice is the longest day of the year, when the sun reaches its highest point in the sky. In the UK it falls around 21 June. At Stonehenge, the solstice sunrise aligns with the Heel Stone and an annual public gathering marks the occasion. After the solstice, days begin to shorten until the winter solstice in December. The meteorological summer begins on 1 June, a few weeks before the astronomical solstice.
