There’s an article over on the New Scientist website about a new calendar system that keeps the same days on the same dates, but it looks completely useless to me, as it requires arbitrary decisions about lengths of months, and also requires an “extra week – which is not part of any month – about every 5 or 6 years.” Huh?
I have long been an advocate of a lunar based system of 13 months of 28 days each, which comes out to 364 days, so every year would have a leap day, plus the standard “every four years unless the date is divisible by 400” leap years. The beauty of my system is that every month is the same, and every month is exactly 4 weeks. It’s so elegant that all I can think of is they liked 12 a whole lot better than 13 for superstitious reasons. I would also name the months “First,” “Second,” “Third,” and so on, so that you’d never have to do that awkward “August is the 8th month” conversion.
