What If Your Birthday Was On Monday Every Year?

So the Gregorian calendar is kind of a pain, right? 30 days has September, April, June… and all that? Who can even remember that? Most of it doesn’t even rhyme.

A new calendar proposed by two scholars from Johns Hopkins University would eliminate the need for that little ditty. Though you might need a new one: September, March, June and December would have 31 days. The rest would have 30. But even better, the calendar would be identical year to year, so Christmas and every other holiday would fall on the same day of the week annually.

Richard Conn Henry, as astrophysicist, and Steve Hanke, an applied economist, came up with the calendar and think we should all adopt it. Besides making life simpler when it comes to planning annual events and work holidays, Henry and Hanke also say the new calendar would have profound economic benefits.

Because the calendar would be the same year to year, financial calculations would become much easier. Hanke explains:

Determining how much interest accrues on mortgages, bonds, forward rate agreements, swaps and others, day counts are required. Our current calendar is full of anomalies that have led to the establishment of a wide range of conventions that attempt to simplify interest calculations. Our proposed permanent calendar has a predictable 91-day quarterly pattern of two months of 30 days and a third month of 31 days, which does away with the need for artificial day count conventions.

Henry and Hanke say their calendar is an improvement over other proposals because it doesn’t change the seven days per week cycle. Western religions that mandate a day of rest don’t like that because it violates the Fourth Commandment mandate for having a Sabbath. But considering that we’re a country that still uses inches, feet, and yards, I can’t imagine a big calendar change happening anytime soon. And what about those poor bastards who will have their birthday every year on a Monday? And if your birthday happens to be on January 31 (or one of the other months that now would have just 30 days)? Hanke and Henry suggest: “celebrate your birthday on a date of your choosing!”

    How would this even work? 7 does not go into 365 evenly, so what would happen when you got to December 31st of december (say a wednesday), would the 1st of January then need to be changed back to a (say) Monday? I assume they are still working on a 365 day year? Where do leap years fit in? Wouldn’t you need to have that day of the week twice, so the 1st of March would be on the same day as it was the year before.

    Crazy…

      If you follow the link to the article you will see that they would shorten the year to 364 days and then have an extra week at the end of December “every 5 or 6 years”.

    As long as they make Christmas & boxing day on a Saturday/Sunday so we get two bonus public holidays, then it sounds fine.

    These articles come up every year….

    Same with Summer time, people dream up articles to make time stand still for a little longer…
    Then we all go on with the same..

    Time is just an illusion…. Who is going to staff the world for that extra week….

    It is hard enough having an extra day in the year…

    Why not go for the Lunar year cycle, with an extra month every 10 years or so…. 28 day months are good, and it makes the year even shorter….. (oope it has to be fixed every decade….

    As with UTC… We already Use this (GPS activaed devices especially), it is just that we tend to put local time overlays on top of it… so the poor humans can relate

    Sure everyone in The UK will go to work at will go to work at 8.00 and everyone in the USA will head off to work 5-8 hours later at 13:00 through to 16:00 …..

    We are Humans we can adapt to anything….. (cows too)

    Hey why not just go back to using the sundial for time…. revolutionary thing that…. and the crop plantings and harvests to govern months and years.. revolutionary that too…. Pity the ancients have been there before…. not so new…

    Or Universe-al time, as in to do with the universe, why make London the time datum of the world…. Everyone has a nut-case idea in there somewhere, we shouldn’t call people geniuses Just because they have a stupid idea that we would have never thought of….

    I have no ide where they pull this “establishment of a wide range of conventions” crap from.

    There is an ISO standard for date and time notation.
    http://en.wikipedia.org/wiki/ISO_8601#Ordinal_dates

    Ordinal Dates are a simple substitution of a date to a number between 1-365/6. This allows calculation involving dates which is not complicated at all.

    I’m against this, the overall change would be more problematic throughout the transition than just sticking to the Gregorian Calender, people are used to it, why change? It seems more like these two individuals want to be immortalized in history and thus are not thinking things through justly. I mean honestly, there’s no need to change, just a want, and as long as it it a want and not a need, I see no reason to change.

    1) You still have countries using imperial measurements, or incorrect dates (lol, American dates) and anyone thinks there is a remote chance of this?

    2) This would be balls, especially if your birthday was on a Monday :p

    I simplified a few things:
    http://craytoncreation.wordpress.com/2012/01/02/double-week-calendar/

    The big thing is that we all agree we don’t want our birthday to fall ON the same weekday every year. But, if we think of our birthday AS a weekday (as opposed to a number) then we wouldn’t be perturbed.

    The question then becomes, can we stop thinking of days of the month as numbers and begin thinking of them as “the Third Tuesday of July” and so forth?

    [Of course we'd still number days of the year for legal/financial reasons, we just wouldn't use those numbers in everyday life]

    Novel idea, but the thought of having ‘an extra week years every 5 or maybe 6 years’ doesn’t really work imo. The current leap year cycle makes it easier to determine which years will have an extra day as it’s always the 4th year. With this proposed calendar, people would have to remember which years are different.

    Not gonna happen.

    It may have some economic benefits, but it would cost tens of trillions of dollars to implement, think of all the software systems that would have to be updated, it would be a nightmare, think Y2K x a million.

      Tens of trillions? Implement the new calendar at work (without numerical days) and see if anyone notices.
