How old is “Thirty days has September…”?

Gregorian calendar, nursery rhymes, Wales, SeptemberEvery school child learns the months of year with an easy rhyme: thirty days has September, April, June, and November. All the rest have thirty-one, except February alone… How exactly does it end? We’re not entirely sure, but the first lines continue to help us remember the idiosyncrasies of our calendar. (Rhymes or phrases that help you remember something are called mnemonics, named after the Greek goddess of memory, Mnemosyne.)

This mnemonic helps us keep our months and days straight. But where did it come from? The rhyme has been attributed to many different sources, including Mother Goose, but a Welsh scholar may have uncovered its earliest source. It turns out that the poem actually dates back to 1425. However, the words have changed slightly. Originally, the poem read: “Thirty days hath November, April, June and September…” Since November and September rhyme and they have the same number of syllables, they can easily switch places in the poem. The usefulness of the rhyme continues even as its internal linguistic conventions change. We’d never say “hath” nowadays, so the poem has evolved to reflect our current variation of hath: has.

This poem also obviously relies on the calendar staying the same. We’ve been using the Gregorian calendar (and its similar predecessor the Julian calendar) for quite some time. Recently, though, an economist and an astrophysicist at Johns Hopkins University developed a new calendar that would not require a leap year and would make dates occur on the day same every year. They still have to think of a new rhyme.

Can you think of other useful mnemonic devices that rely on rhyme and word play? Have you ever made one up? Are there any questions you have about them?

Supreme Court to Review Insanity Defense [Correction 4/25/06]

The Washington Post April 20, 2006 | Charles Lane The Supreme Court embarked on a potentially far-reaching review of the insanity defense yesterday, as the justices heard oral arguments in the case of an Arizona man, Eric Michael Clark, who was suffering from paranoid schizophrenia at the time he shot a police officer to death.

At issue in the case is whether Arizona’s version of the insanity defense, which requires defendants to prove with “clear and convincing” evidence that they were too mentally ill to understand that their conduct was wrong, is so narrow that it violates the constitutional right to due process of law. go to site insanity vs p90x

Clark’s lawyer, David Goldberg, told the justices that the law denied Clark an opportunity to show at trial that, even if he was able to tell right from wrong, he could not have formed the requisite criminal intent — in this case, the intent to kill a police officer.

Goldberg said that due process requires allowing a defendant to prove that, whatever his sense of right and wrong, he did not grasp “the nature and quality” of his acts. Goldberg noted that at the time of the killing, Clark was obsessed by the idea that aliens were stalking him and that he might have thought he was defending himself from an alien when he shot Flagstaff, Ariz., police officer Jeffrey Moritz.

Clark is supported in the case by the American Psychiatric Association and the American Psychological Association.

Arizona counters that its law gives defendants ample opportunity to introduce the relevant evidence of their mental illness. The state is backed by the Bush administration, which argues that, although the federal insanity defense law is more broadly worded than Arizona’s, Congress’s discretion might be limited by a ruling in favor of Arizona. A brief from 16 states also supports Arizona, arguing that a broad ruling in Clark’s favor “will call into serious question the validity of the majority of state insanity statutes.” Although the insanity defense has deep roots in English common law, the Supreme Court has never ruled that the Constitution requires it. Many states revamped their insanity defense laws after a jury’s finding that John W. Hinckley Jr. was not guilty by reason of insanity in the 1981 attempted assassination of President Ronald Reagan. Four states — Idaho, Kansas, Montana and Utah — have abolished the defense.

Arizona toughened its law in 1983 by raising the defendant’s burden of proof, and again in 1994, when it replaced the “not guilty by reason of insanity” plea with “guilty except insane,” the plea Clark entered.

If he had been found guilty except insane, Clark would have been committed to a mental hospital. Instead, he was found guilty of first- degree murder and sentenced to 25 years to life in prison. insanityvsp90xnow.com insanity vs p90x

The court’s decision to hear Clark’s case, which was summarily turned down by Arizona’s Supreme Court, suggested that some justices saw insanity law as ripe for judicial review. But there were signs yesterday that they might be having second thoughts.

“I thought some of these questions might be in this case, but now I’m having doubts about that,” Justice Stephen G. Breyer remarked.

Breyer noted that much of the evidence of severe mental illness that Clark would use to prove his delusions about aliens would also be introduced as part of proving whether he knew right from wrong.

Seeking to reinforce that point, Randall M. Howe of the Arizona attorney general’s office told the court that “it would be difficult to imagine a situation where someone knew right from wrong, but not the nature of his act.” Justice Anthony M. Kennedy agreed with Howe. “I’m trying to think of some hypothetical where it would make a difference, and I can’t come up with one.” But Justice John Paul Stevens challenged the state’s position, asking Howe whether someone could be found guilty if he thought he was shooting a Martian and believed that killing Martians was acceptable.

Howe conceded that he might have a strong case of insanity but quickly added that “a state has a right to define insanity as it sees fit.” The case is Clark v. Arizona, No. 05-5966. A decision is expected by July.

    I’m so glad someone mentioned Calendar Man in Arkham City, because that’s who I think of whenever I hear this. He cites it as: Thirty Days hath September, April, June, and November. All the rest have thirty-one, Except for February alone, which has twenty-eight rain or shine, but on a leap year, twenty-nine.

    I’ve read about the article of “the new calendar”, it’s interesting though but rediculous, imagine having the same date on the same day (ex: Dec. 25 is Sunday) then it would always be the same over and over again as the years pass. That I don’t want to happen having the same date of birthday on the same day again every year, of course if I was born on Monday, I don’t want to my yearly bithday to be in the same Monday for the rest of my life, it really is stupid..

    It was long ago/far away and learnt it from my husband to know and tell how many days in a month: 31 days or less (though February has its own system of taking two).

    Just like Anonimous I was taught to go by my knuckle-way. Yes, starting from the index finger, the CREST, let’s name it, having 31 days, so other finger crests follow suite too of having 31 days. In between two fingers, that is the index and middle one (or between the middle and ring) VALLEY, they are of less, 30, 29 or 28. (The last two in the case of February having two versions; I liked and enjoyed Collete, Debbie, Dusty, Sue & Abi’s poem very much on this distinctive month).

    The requirement is of other such ….
    Well now… a couple of them perhaps and that are not rhyming, perhaps kind of mnemonics and useful:
    Badmas (algebra);
    Fanboys (grammar); and
    Vibgyor (the rainbow colour).

    Teachers – particulary Special Ed – why are you not incorporating more
    mnemonics in your lesson plans. Certainly as educators, you
    are aware that any information entering the brain using 2 or
    more senses is absorbed at a higher rate. If someone is
    reading (or writing) a mnemonic and saying it, the chance of
    it moving to long term memory is increased dramatically.
    Some of the best educators/instructors/lectors all use
    mnemonics, acronyms & humor. Tune in to Sesame Street and
    take note.

    Somehow I was never taught this rhyme. A method I learned for determining the days of the month used the knuckles (and the valleys between each) on my fist: all the high points (knuckles) are months with 31 days; all the low points (between each knuckle) are months with 30 days — except February, of course. Obviously, we do not have enough knuckles to accommodate all 12 months, so when you reach the last knuckle, you simply start over at the first, which nicely matches up with July/August, the two back-to-back months with 31 days.

    I make a fist and use the knuckles and the space between the knuckles of my hand to remember how many days each month has. Starting on the first knuckle (not using the thumb) for the first month, it is higher than the next one, so January has 31 days. The ‘valley’ between the first and second knuckle represents February, which has 28 or 29 days (depending on whether it is leap year). The next (second) knuckle stands for March, which has 31 days, and so on. When you get to the knuckle for the little finger, it represents July, which has 31 days. Then you start over on the knuckle for the first finger which represents August, which has 31 days. I think my grandmother taught me that.

    Another thing, “Anonymous”: most people — even musicians! — never figure out that the order of the sharps and the flats is exactly reversed, but your mnemonic makes it abundantly clear. (Nice job! Even though the second “Father Charles” — the “flats” — is in the wrong sequence.) I’m always glad to learn something new.

    There were 26 comments preceding mine, and not one of them correctly quoted the rhyme. It is:

    Thirty days hath September
    April, June, and November
    All the rest have thirty-one
    Except February in fine
    ‘Til Leap Year gives it twenty-nine!

    “Closed-circuit for “Me”: Yes, they were still using the Julian calendar in 1425. Great Britain and all her colonies (which WE were at that time) adopted the Gregorian calendar in October of 1752 — 24 years prior to the signing of our Declaration of Independence.

    For “Anonymous”: The musical flats are BEADS (the letter S looks a lot like a G in script) — B-flat, E-flat, A-flat, D-flat, G-flat. If you get to six or seven flats, it’s easier to remember which notes are NOT flats! The sharps are easily remembered by this mnemonic: “Fried Chicken Good Dinner Always.” i.e., F, C, G, D, and A. (The same caveat applies to the sharps as to the flats — after the first five, it’s easier to remember which notes NOT to flat!)

    In case you hadn’t figured it out, I AM indeed a musician. I play ‘cello in a number of other venues. (I play other instruments, but when folks know you can play ‘cello, they’re not interested in anything else.)

    I remember about a million years ago, one of my weekly spelling words was “arithmetic” – and our 2nd grade teacher, Miss McNamara, gave us this mnemonic device. By reading across the initials of each word, we could remember how to spell it correctly:

    A rat in the house might eat the ice cream = Arithmetic

    …and to this day, whenever I read or write that word, I think of her. She got married when I was in her class that year, and she changed her name. So…

    It’s amazing (and annoying) how many people do NOT read the comments of others before them. Check how many nunus repeated the same story … sigh

    Here in our country, it goes like this:

    30 days has September,
    April, June, and November.
    All the rest have 31,
    except February which has 28.

    Leap year comes one year in four,
    and brings to February one day more.

    English, Primary shcool in the seventies – and also Irish parentage – my learned version ends a little differentlyly and goes something like this: Thirty days hath September, April June and November. All the rest have thrity one except February which has twenty eight, although every one in four February has one day more.

    I like how this is dictionary/thesaurus.com, yet in the picture that they used to represent this article, they misspelled February… Just sayin’.

    We were taught a slightly different and shorter/easier version in my hometown back in the 70s. And still today, when my kids were in Kindergarten, they were taught the same way through the public school system:

    30 days has September, April, June and November.
    All the rest have 31,
    Except for February, it has 28.

    How recently did the Welsh scholar discover it? The “Welsh scholar” article is dated Jan 16th 2012, but I’ve known the “hath” version since I was eleven or so:

    Thirty days hath November, April, June and September.
    Of twenty eight is but one,
    And all the rest are thirty and one!

    I think I learned it from a Middle English lyric book my grandparents used to have… It’s very neat a poem like that is still common 600 years later!

    Huh. I guess you learn a knew thing everyday. I especially liked the whole Greek goddess of memory thing; who would’ve known that the word “mnemonics” was derived from that?

    Nursery rhymes are quite useful for us to learn something when we were children.

    I count my knuckles to remember the days of the months, starting on that of the index finger – if it’s on a knuckle it’s 31, if it’s in the hollow it’s 30, 29, or 28. There’s also ROY G BIV for the colours of the rainbow and Father Charles Goes Down And Ends Battle/Battle Ends And Down Goes Father Charles for the order of sharps and flats.

    We should just get a new callender that has a really simple way to remember and they should all start on the same day like sunday that way people still get to freak out about friday the 13th. Or we could use the full moon as a guide and every 12 cycles could be a new year, the months would be named Ira, Moro, Thuna, IMT, Ock, hanu, Eyroc, Tanu,Anu, Rom, Unaht,and Kcori. People wouldn’t need a rhyme

    Thirty days has September, April, June, and November.
    All the rest have thirty-one,
    Except for February alone,
    And that has twenty-eight days clear,
    And twenty-nine in each leap-year.
    That’s how it ends :)

    Well, the ABC song is made in such a way that it rhymes…G, P, V, and Z all rhyme and are at the ends of the lines.

    I usually make mnemonics when is was studying. like this: sine is to year, cosine is xer, tangent is yex! ( i have a tone on this one while singing. Obviously, I couldn’t sing it in here). Well, my mnemonics means this: sine=yr, cosine=xr, tangent=yx. Then, I have good scores is trigonometry class!

    As a student of geology, we had to find a way of learning the sequence of geological periods (Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous, Tertiary, Quaternary). This was done by saying “Can old sods drink cast port? They can’t. They quit.” The 3 sentences also usefully separated the three main eras (Palaeozoic, Mesozoic, Cainozoic).

    ” … which has twenty-eight days clear, and twenty-nine each leap year.” Just in case you were interested.

    I remember a different way that i remembered the months. i remembered how many days there are in each month because I’m smart like that. but the way i remembered the months were just singing “January..Febuary.. March.. and April, May, June & July. August.. September… October… November… December, these are the months of the year… these are the months of the year” it went something like that. LOL

    This made me think of Frère Jacques. In French it begins with brother John, brother John, but in English we start with Are you sleeping &c. That is not a mnemonic, but it is interesting how the tune plays a role in the word choice. Did we still use the Julian calendar in 1425? Do you think that there was a similar rhyme when we used the Julian calendar (there were I believe only ten months)?

    I learned it as, “Thirty days hath September, April, June, and November./ All the rest have thirty-one, except February alone/ Which has twenty-eight days clear/ And twenty-nine each leap year.” … Like this year.
    Anyway, that refutes the previously made point, that no one says hath anymore (and have they forgotten all of the actors in various works by Shakespeare?).
    Other than all that, interesting read.

    I was raised in the U.K. and the rhyme that we learned went as follows:

    30 days hath September, April, June and November. All the rest have 31, excepting February all alone has 28 days clear and 29 in each leap year.
