The event is primarily any Celtic fire festival, midsummer representing the centre of summer, and the shortening from the days on the gradual 03 to winter months. Midsummer is usually celebrated about either the particular 23rd as well as 24th involving June, although the longest day time actually falls on the Twenty first of June. The importance of the afternoon to our ancestors can be traced back thousands of a long time, and many stone circles and other ancient monuments tend to be aligned on the sunrise on Midsummer's Day. One of the most famous place is that in Stonehenge, where the sun's rays rises in the heel gemstone, framed by the giant trilithons on Midsummer morning.
