I’ve never been a big fan of the short number of hours of daylight in the winter time. In Indiana, at the far Western edge of the time zone, the sun would rise really late in the morning. I found that very depressing. It was so hard to get up in the pitch black.
Nagoya is on the Eastern edge of the time zone, so the sunrise is relatively early. In the summer it is crazy early, and the sunlight wakes me up pretty easily. I’m able to get out of bed, and get going quickly. In the winter though, it is still dark, my room is cold, and I am uninspired.
But now, we are at Solstice, the minimum number of day light hours for those of us North of the Tropic of Cancer, or the sun’s lowest inclination angle. From now until the end of June, the number of daylight hours will increase as the sun appears to take a Northerly trek in the daylight sky. The sin wave is very flat for a while so we are not out of the woods yet, but it is improving. Or will be about 9 hours after I post this.
