So what is wrong with this calendar that the US Congress proposed? We have this steady progression of every seven days and all of a sudden we have eight days between one Sunday at the end of the year which just happens to be the last day of the year and the next Sunday because of that extra day. The same holds for Saturday or any the day of the week. From one day of the week to the next they are always seven days during the year but from one year to the next we have eight days. And then every leap year we have an additional eight days instead of seven.
I would think they could just adjust but tradition is far more powerful than intelligence. I can remember watching the original Around the World in Eighty Days and watching Phileas Fogg arguing with Passepartout: "I have kept a careful record and this is the 81st day." But they had gone around the world, always traveling east. They had crossed the International Date Line. But it does give one pause for thought. How does this impinge on this insane idea of every seventh day? If we are to be literal, Phileas Fogg is correct. Sunday for him is now one day ahead of everybody else. So they can stick that in their date calculations of what is when and perhaps move Christmas to that end of year day that is not part of any week. What made Christmas to be on the 25th of December and Easter when it is? People did and they can change it if they want to.
So what does this have to do with Daylight Saving Time? You can see there are problems when you move around the earth. You can also see that beliefs are much stronger in opposing something that works better. Okay, now you at least know of an alternate calendar that could be used and IMHO, should be used. I can guarantee that it won't be used for at least another 400 years though.
