Tomorrow, time is going to be changed; the daylight saving time is starting. Tomorrow's early morning 2am is going to be 3am. It is called Spring Ahead. (When the time was changed in the late October, it was called Fall Back.) Yes, we are going to lose an important hour to sleep.

I heard it is good for the environment or economy. I am not sure if Japan should bring in the summer time system. I think we did introduce it for a long time ago, but it failed at that time. (I think it was before the WWII.) Time to time, it seems to be discussed on the political arena. My impression is that it is confusing for a while after the time is changed, but soon we forget about the change. If it is really good for our environment, I think it is worthwhile thinking about the changing.

Anyway, it is so sad to lose an hour to sleep (or maybe study) more.
