Summer solstice is the longest day/gets most direct sun light. Doesn’t that mean the warmest season is 1/8 year before and after it? So summer solstice should be the middle of summer instead, right? Or is there delay between sunlight hitting earth and earth getting warm?

If the solstice and equinox days were the middle of season, they couldn’t tell when exactly the season begins. But these special days were great markers for seasonal change. It was convenient.
The same goes with the beginning of a new year on January 1st, of the 30 day long months with only February at 28 days. That for example, had been set by Romans who believed February is an unlucky month and therefore shortened it.
