Reply to comment by wubbbalubbadubdub in Spring and summer have almost the exact same amount of daylight hours because the longest day falls on the first day of summer by youpviver

Um what? We know the tilt of the axis is what changes the daylight hours.

And Summer is literally defined as starting on the Summer Solstice. All the seasons officially start on their solstice or equinox.

Summer is warmer than spring because the (average) temperature is a bit laggy. The longer days take a while to actually get the surface to warm up.

Nobody seriously bothers with that definition of the seasons, Meterological seasons are overwhelmingly more common. First day of summer is June 1st.

My calendar app shows June 21 as the first day of summer, and so do my paper calendars. If you Google “first day of summer, 2023” it shows you “June 21st, 2023” before you are even done typing. We just had the first day of Spring last Monday (on the equinox) which was a semi-big deal because of how rough this Winter was.

I have no idea where you are getting June 1st from, I’ve never heard of seasons starting on anything except the equinox/solstice. It lines up reasonably well with the noticeable warmer/cooler weather due to the lagginess of the average temperature.

That's according to the meteorological definition of summer rather than the astronomical one. Both are used across the world, but I've also only considered June 21st to be the start of summer.
