Two professors, an astrophysicist and an economist, propose junking the leap day dependent Gregorian Calendar for a 364-day (52-week) year and a leap week every once in a while.
Should this year's "leap day" be the last one? Yes, say some scholars who have analyzed the complexity of the Gregorian Calendar on which humanity now relies.
That calendar includes the familiar 12 months of varying lengths, with February punctuated by an extra "leap day" every four years (except, to be precise, in years that end in 00, which are governed by slightly more complicated rules).
"Holidays occur on various days of the week, changing each year," Mr. Eastman wrote in 1926. That wasn't just a nuisance, he said. It also meant added costs for businesses trying to arrange their schedules.
Enter two professors at Johns Hopkins University, one an astrophysicist and one an economist, with what they think is a better way for us to manage our time.
Richard Conn Henry and Steve Hanke argue that 2012 should be the start of a new calendar, in which Christmas always falls on a Sunday and lots of other things also get simpler, from planning a birthday party to calculating interest on a mortgage.
They say a simpler calendar will be better for the economy and society. Although leap days would disappear, this new calendar still needs a solution to the problem that Earth's annual circuit of the sun doesn't divide easily in a year of seven-day weeks (or of 365 days, for that matter).
The proposed 364-day (364 is divisible by 7) Hanke-Henry permanent calendar would ignore this issue during most years, and add a week-long "mini-month" (call it a leap week?) at the end of December every five or six years.
Other than that anomalous week, which they dub Xtr (or Extra), each year would be made of up four 91-day quarters (still totaling 12 months, eight of them having 30 days and four having 31 days).
