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).
...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.
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.

We almost got there in the late 70's. Fortunately, Reagan swooped in to save us from having to drive 370 kilosocialists from DC to NY. But you're in luck. If you really want to use the metric system exclusively in the US, just join the military ( http://en.wikipedia.org/wiki/Metrication_in_the_United_States )
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.

It wasn't Reagan, per se, but the fact that there is so much military hardware out there and being maintained
already the the conversion of theses systems are darn near impossible. It's not a matter of replacing a 1/4"x20
bolt with a "metric" equivalent measurement; all of those engineering drawings, etc, would have to be converted.
Plus all of the supporting tooling, etc. At the time (70's) it would have been far easier to convert the world to
U.S. standards.
Reagan just tabled the obvious.
For every day use, all you need is to have a sense of how much a unit is.
Here's a handy guide.
As someone who's grown up with the metric system (Europe), I can assure you that it works just fine for 'normal activities' :) I think in the end it's just a matter of getting used to it. And frankly, I do understand why people resist it, because people who didn't grow up with either system are probably never going to get 'used to' the other system and be able to easily use it for everyday things.. that will have to come with the next generation of people that grow up with it
I was in my teens when my country switched form their native currency to Euros, and I still catch myself translating prices to the old currency in my head on occasion, to get a better sense of prices. Having to do that for all sorts of measurements would be hugely annoying I can imagine.
Ummm... According to the guide, a two-liter bottle holds three liters.
Or star trek like translators that convert units in real time, so each of us can be maximally free to use whatever system we choose.
Apparently NASA didn't get that memo.

Um, you might want to check that. Equinoxes (and solstices) mostly are. The only variability is because the terrestrial orbit is about 1/4 day longer than an integral number of days, but the effects of that are kept to a minimum due to leap years. We have an approximately astronomical calendar.
That the 7-day social cycle doesn't fit into the 365 day calendar is the source of most of the perceived and actual variation in dates (eg, American Thanksgiving is always a Thursday, President's Day is always a Monday, etc., which means those dates will never be the same from one year to the next), in addition to events which are determined by lunar cycle (like Easter, Passover, or Ramadan) which also doesn't neatly fit the terrestrial orbital period.
But as for equinoxes and solstices, they're mostly stable, varying by date only between two neighboring days. See http://en.wikipedia.org/wiki/Equinox .
