Quantity

Days getting longer
Looking out of the window down a busy street in the twilight, something occurred to me. The days are apparently getting longer. When I came home I checked out the sunset time in Tokyo. It was 4:38 on the New Year's day. One month has passed and it has got 5:07. Thirty minutes longer. How much longer do you know it will be in the midsummer day (the summer solstice) ? Answer is 2 and half hours. It means the daytime is 5 hours different between the winter and summer solstice. Wow this is something.
We all qualitatively know that in summer we have longer daytime and shorter in winter. But sometimes isn't it good to give it a quantity and realize the length?
