I've just spent a few hours reading up on The World Calendar and Decimal Time, which are both ideas I very much like.
The World Calendar is great because you'll never have to buy a new wall calendar again, the same one works every single year. Your birthday or anniversary will be on the same day of the week every year. The year ends on Saturday, there's a Holiday day, and then the new year begins on Sunday. Leap Year days are between Saturday and Sunday as well. It is simple. It is tidy. I'm in love with Calendar Reform.
I ran across decimal time because i get really annoyed at time conversions in my physics homework. There's a different conversion each step of the way to from days to hours to minutes to seconds. Yes, it is pretty common sense, but why have another thing to know when we are already learning x10 prefixes for every single other unit of measurement? Dumb. Annoying. Do away with it. In reality, if that happened I know we would be forced to learn how to convert from Wacky Time to Decimal Time, thus adding complexity rather than eliminating complexity. A Geek can dream, okay? I'm willing to bet (or remember) that it is already the case that some science uses decimal time. No, I won't look it up. Who do you think I am?
Then I ran across this selection of funny clocks at Dick and Jane's Fine Woodworking. On the 4th and 5th rows are: Who Cares?, Don't Do Mornings, No Drinking Before 5, Further I Go Behinder I Get. They also have one Decimal Clock.
