What happens at the summer solstice
The summer solstice is the day with the most daylight in the northern hemisphere, when the Sun reaches its highest point in the sky. It usually falls on 20 or 21 June. In the UK the day length is around 16 hours or more depending on how far north you are, and in Shetland the sky barely gets dark. The solstice is celebrated at Stonehenge, where thousands gather to watch the sunrise over the Heel Stone, and it has been a significant date in many cultures for thousands of years. In the southern hemisphere the same date is the shortest day of the year.
