Christmas Always On Sunday? Researchers Propose New Calendar

An anonymous reader writes "Researchers at Johns Hopkins University have discovered a way to make time stand still — at least when it comes to the yearly calendar. Using computer programs and mathematical formulas, an astrophysicist and an economist have created a new calendar in which each new 12-month period is identical to the one which came before, and remains that way from one year to the next in perpetuity."

    Jan 1 = Sunday, 30 days
    Feb 1 = Tuesday, 30 days
    Mar 1 = Thursday, 31 days

    Apr 1 = Sunday, 30 days
    May 1 = Tuesday, 30 days
    Jun 1 = Thursday, 31 days ...

    Then every 5-6 years, there's a leap *week* at the end of the year after December called Xtr, so Xtr 1, 2015 through Xtr 7, 2015 would exist as valid dates (in whatever order your country uses).

      I remember a lecture where they went over why the months have the number of days they do. I'm not sure this is entirely accurate but at least it helps me remember what months have how many days.

      It was a 10 month calendar where it alternated between 31 and 30 days and started in March (Mars) which was the start of nice battle weather and ended in December and they just didn't bother counting the days in winter and waiting for spring to arrive. Eventually January and February were added to the end. to get this.

      1 March 31
      2 April 30
      3 May 31
      4 June 30
      5 Quintilis 31
      6 Sextilis 30
      7September 31
      8 October 30
      9 November 31
      10 December 30
      11 January 31
      12 February 28 basically whatever was left over.

      Notice the first 4 months are named after Gods. So when Julius Cesear came to power he renamed the 5th Month July after himself. Then they also changed the order so it started with January.
      Then Augustus came to power and took the 6th month. But he didn't want his month to be shorter so he changed it to 31 days and changed the rest of the months
      to alternate from 30 to 31.

      So that is why the months have the number of days they have.

      Why should that matter? Christmas is a national holiday in the US (meaning it is defined by law as such), anyone regardless of religious preference should get the day off. (Or get paid double pay.) I'm an atheist BTW, my family never went to church, I have celebrated Christmas my entire life, and I love the holiday. Christmas is a day to get together with friends and family, enjoy the lights and trees and decorations, and exchange gifts with your loved ones.

      Contrary to what some would like you to believe, Christmas is not necessarily a "Christian" holiday to everyone.

  2. Each 12-month period is not identical by rminsk · · Score: 4, Informative

    ...have created a new calendar in which each new 12-month period is identical to the one which came before, and remains that way from one year to the next in perpetuity.

    and then later in the article

    This adjustment was necessary in order to deal with the same knotty problem that makes designing an effective and practical new calendar such a challenge: the fact that each Earth year is 365.2422 days long. Hanke and Henry deal with those extra “pieces” of days by dropping leap years entirely in favor of an extra week added at the end of December every five or six years.

    So it does not remain consistant from one year to the next.

  3. What, ANOTHER "leap week" calendar? by dpbsmith · · Score: 5, Informative

    There have been many calendar-reform systems proposed, and "leap-weeks" are a common solution. Wikipedia has an article on leap week calendars and lists five advantages and three disadvantages. It, in turn, points to a web page about leap week calendars that details nine of them.

    Henry's own web page doesn't mention the existence of other leap week calendars. It merely says the Hanke-Henry Permanent Calendar is better than the Gregorian calendar, not why it is better than the nine other leap week calendars. And it doesn't seem to present any particular plan for getting it adopted, beyond saying "It CAN be done, folks, and the decision is YOURS, not mine. Each of you," and the proof that it's feasible is that his mother has adapted to quoting Celsius temperatures. But what's needed is not a better calendar, but a better plan than anyone has heretofore come up with for getting it adopted.

  5. Time Zones... by Lt.Hawkins · · Score: 4, Informative

    Eh, not bad at first glance, but I can't be on board with zapping time zones. As someone who deals with international locations across the globe every single day, its a ton easier to find out "oh, they're 8 hours behind us" vs "Hmm, its 0900 Global. We just had lunch... what are they doing in New York at this time? Its 0900 there too - I think its still dark, but I don't know if its close to dawn or if they just woke up."

    Sounds good in theory, but god it would suck.
