I wrote a little program to visualize my sleeping habits. The data is held in a Google Sheet, and the program is written in Python3. The graph is generated with matplotlib.

Back in 2021, I read a few articles on the quantified self. The quantified self is to treat one's lifestyle as a numbers game, usually supplemented by analysis or optimization. This isn't exactly how I wanted to direct my life, but I was interested in tracking something, just to see how it would develop long-term.
I knew I liked staring at the sleep tracker on my phone, but it wasn't very accurate as it assumed I would fall asleep before a set bedtime. So, I started tabulating my sleep and wake times on September 21, 2021.
Here's my chart for 2021, starting on September 21:
I also calculated some bonus statistics on the side. The shortest sleep during this time period was 5 hours and 45 minutes, on December 30. The longest sleep was 10 hours and 40 minutes, which actually occurred three times in December.
On average, I fell asleep at 2:21 AM and woke up at 10:38 AM. But, I got about 8 hours and 17 minutes of sleep per day, which is healthy, I think. If I ever move to California, I would adjust very easily.
Now here's my chart for 2022, up to July 16 (can you guess when I started my 9 to 5?):
One interesting observation was that my sleeping habits appeared periodic. For a few weeks I would sleep super late, then ease back into earlier hours. I'm not sure why this happens.
