I woke up an hour earlier today. Daylight Savings Time ended on the weekend. Since the last time we moved to Daylight Savings Time, I have not set an alarm to wake up. I use my internal clock to wake me up. Before going to sleep I tell myself how many hours I will sleep, and what time I will wake up.
This morning I woke up an hour before I had planned to, yet at the same time as I usually wake up. Does this how, anecdotally, that my internal clock takes time to adjust, even though I told myself how many hours to sleep and when to wake up?
I would much prefer that we did not change our clocks twice a year, and stayed on either Daylight Savings or Standard Time.
