The summer solstice is upon us. This year, it falls on Sunday, June 21, also Father’s Day. Our longest day and shortest night mark the beginning of astronomical summer. Celtic traditions call for the lighting of bonfires on this night to help strengthen the sun as it begins to wane. The solstice is followed by a full moon on June 29, called the “strawberry moon” in the Farmers’ Almanac, reminding us of berry season.
