It's not really the start of Summer; it's Midsummer for a reason. The days (sunlight) start getting shorter. The seasons have many different definitions; Meteorological summer started on June 1st; back in the day, Summer started on May 1, thus mid-June was mid-Summer according to that calculation. Personally, I follow the meteorological dates (Dec. 1, March 1, June 1, and September 1) to reckon the seasons. The Summer Solstice is fun and has a rich folklore, but for me, it doesn't mark the start of Summer.
