One of the first signs of the changing seasons I notice in my office 🏣

My corner office is on the north-east side of Smith Building downtown. In June and July for much of the work day, the sun radiates into my office necessitating the window shades be closed, especially on hot days. But come later in July, heading into August by mid-day the sun is far enough to the south and west, that on cooler days, I can have the window shades open and a cool blue light coats the the office as I rarely use the overhead lights. Come September and especially in October and November, I will have to use my desk lamp more, especially as the time change approaches.
