June is when summer officially clocks in. The solstice lands on the 20th or 21st, Pride Month runs the full 30 days, Juneteenth marks the 19th as a federal holiday, and Father's Day shows up on the third Sunday with a tie nobody asked for. It's the longest-daylight month of the year in the northern hemisphere, which means everyone is outside and nobody is answering email.
