    4 weeks. Starts on a Sunday and ends on a Saturday. Since it has 28 days it's the only month where this can happen.

    Why didn't they make all of the months 28 days? Then there'd be 13 of them, with one having 29 days. Maybe because 13 is an unlucky number?

    Because the months are an artificial construct which were *originally* tied to lunar cycles, but then got adjusted to account for various issues, *including* political reasons.

    Unfortunately, the number of lunar cycles do not fit neatly and indivisibly within Earth's solar cycle.

    But now that virtually everybody lives in little artificial boxes under artificial light and virtually nobody even knows what the sky looks like, we should switch to some rational metric system of timekeeping.

    UNIX systemtime, anyone?

    The Western calendar comes from the ancient Romans, who originally simply numbered their months, and named them after Latin & Etruscan gods. Then they later renamed 2 after their deified emperors.

    January = the god Janus
    February = Februa, a Roman rite of annual purification
    March = the god Mars
    April = unknown Latin derivation, possibly meaning "to open" from Spring blossoms
    May = Maia, goddess of Spring
    June = the god Juno
    July = Julius Caesar
    August = Augustus Caesar
    September = 7
    October = 8
    November = 9
    December = 10

    I like the months how they currently are because I know them and don't want to learn a new system.

    "30 days has September...April, June and November...all the rest have 31, except February which has 28, and 29 on Leap Years." Clunky, but I've recited it in my head on more than one occasion.

    I love fucking with people's memories. When they try to say that old days of the month phrase, I'll say something like:

    "30 days has June, August, October, and April, too. Except February, which has none at all."

    And then they can't reconstruct the original ditty. LOL!

    I use my knuckles; make a fist, index finger knuckle is January, between it and the middle finger is February, March is the middle finger knuckle, etc. When you get to the last knuckle, July, then start back with your first finger for August. Between the fingers is 30 or 28 days, the knuckles are 31 days.

    Yeah, I forgot about the lunar cycles. Kind of reminds me of when I realized that the earth spinning on its axis gives us the time for the day while the earth spinning around the sun gives us the time for the year and they're not related or tied together.

    And CE would start January 1, 1970? icon_eek.gif

    As kids, we remembered by using the knuckle. The high points are months with 31 days and the lower ones as those with 30 days, including Feburary.

    And if the 1st day of the month falls on a Sunday, then the Friday of the second week will always be the 13th, regardless of what month it is.

    This year, Friday 13th will be two consecutive months, February and March, but will not occur again until November.

    Not great news for the superstitious...

    What the hell is boxing day? All I know is it's some British holiday.

    The politically correct are already using "CE" as an alternative to "AD." Maybe just "UT?" Call it "universal" instead of "unix."

    "Stardate" would be cool, except that it appears to have been any random number that popped into the episode-writer's head. icon_confused.gif

    I've always been glad February is the shortest month of the year... it hasn't been kind of my family, having lost some members and some illness as well while I was growing up. Also, I'm tired of the winter by this time and am ACHING to get outdoors and enjoy some warm weather (albeit it has been in the 70's here in Kansas over the last couple of weeks and no snow at all here, so not bad).

    Whatever shape it is, glad it is only 28 days...lol

    Sadly, they'd be much closer to lunar cycles if they were all 28 days!

    I also learned the knuckle system when i was young :-) It works!!!

    Well a lunar cycle is roughly 29.53059 days. So it explains those 30 day months. I am still surprised who decided on 31 day months and why february is the only month with 28 days, but 29 days in depending whether the year is divisible by 4 or by 100 or by 400, etc.

    Ah. The joy of keeping our calendar and planetary orbit aligned.

    How long is a year?

    365 days, right?

    Not quite

    365.2425 days.

    So, we round that off, and say that every 4 years, we add a day, so that the calendar doesn't move relative our actual position in orbit.

    *However*...it's not 365.25 days....so if you add a day every 4 years, you get a cumulative error of 3 days every 400 years....

    To get around *that*, Century years (which, since divisible by 100 are by definition divisible by 4) which would normally be leap years are *only* leap years if divisible by *400* (or 1 out of every 4....meaning you lose 3 leap years every 400 - voila)

    My career in the Army was somewhat like living in an alternative Universe, in many ways. But one of those ways was time & date.

    We used a European 24-hour time system, because it was more clear and easy to calculate time increments. If I was told an operation was in 6 hours, and it was currently 1130 hours, I just added 6 and got 1730 which is 5:30 PM in US civilian time. I can still instantly convert between the 2 systems to this day without losing a beat.

    And for the calendar we used Julian dates, which is simply numbering the days sequentially from 1 to 365, except on a Leap Year for 366. This was most often used for equipment service. If something needed a scheduled service at 90 or 120 days from the last service performed, you just added. Try doing that with an irregularly numbered monthly calendar.

    There are also leap seconds which are added every now and then to account for the slowing of the earth's rotation.

    Wow, that's cool. Do they factor in huge earthquakes that wobble the earth on its axis? I'd imagine yes, but don't know.
