About twenty years ago I was thinking of getting a sundial for my backyard.
To set a sundial, you need an almanac. I used The Old Farmer's Almanac. I noticed something interesting. Each solar day is a couple minutes faster or slower than one before and after. This is called sunfast.
Why is that? Is it because the earth spins faster when it is closer to the Sun?
