Today, June 21st, is the Summer Solstice and therefore the longest day of 2014.
Solstice traditions such as lighting bonfires on hilltops stem from activities in pagan times, and many Stone and Bronze Age sites around the world exhibit alignments with the Sun during the solstices.
The exact time of the Solstice is 6:04am Irish time. This is the point when Earth’s axis is tilted most towards the Sun. Because of meteorological lag, the Summer Solstice is often considered to mark the beginning of Summer, whereas in astronomical terms the Solstice marks the middle of the season (hence the name ‘Midsummer’s Day’).
