Feels like it has been Summer since the First of June.
The official start of summer kicks off in the Northern Hemisphere today (June 21), marking the longest day of the year.
This is what I found, along with the image:
The June solstice will occur at 11:32 p.m. EDT (0332 June 21 GMT), when the sun reaches the point at which it is farthest north of the celestial equator. Reaching its highest and northernmost point in the sky, the sun must travel its longest path, meaning it will take longer to rise and to set, which is why today marks the longest day — or longest period of sunlight hours — and shortest night.
