       | Nobody ever explained in school that the reason the numbers in
       | the names of September, October, November, and December (7, 8, 9,
       | 10) don't match up to their actual month number (9, 10, 11, 12)
       | is because the Roman calendar began in March, not January. If you
       | start from March, they line up perfectly. It also explains why
       | the seemingly arbitrary choice of storing the extra leap day in
       | February makes sense--just tack it onto the end!

         | idea came from, after this neat article.

           | 
           | > On Sosigenes' advice, Caesar added another two never-
           | before-seen months to the year 46BC, one of 33 days and one
           | 34, to bring the calendar in line with the Sun. The additions
           | made the year the longest in history at 445 days long, with
           | 15 months.
           | 
           | The two additional months were a one-time-only thing for that
           | year, but I can see wires getting crossed and having that be
           | a thing that was repeated for a while.
           | 
           | July and August were never added, though, simply renamed.

         | Google tells me that Romans did celebrate birthdays. I'm

         | 
         | Did they just count the days of the off calendar time? Move the

             | Thanks, so that does seem to confirm that when the Romans
             | added Jan/Feb, they put them at the beginning of the year
             | right from the start. Unfortunately it still doesn't really
             | have an answer to why they didn't put them at the end,
             | except that it fits with the chosen name (Janus = God of

           | There were different standards in Europe during the middle
           | ages and early modern period. Some places retained a date
           | closer to the Roman New Year around the vernal equinox. These
           | places used the Feast of the Annunciation (March 25). Other
           | places (usually in the north) inherited a date closer to the
           | winter solstice and so they used the Feast of the
           | Circumcision (January 1).
           | 
           | As trade between countries grew during the early modern
           | period countries began to standardize on the Feast of the
           | Circumcision. England was a holdout, though and if you look
           | at record from the first half of the 18th century, they will
           | often include both years for dates between Jan 1 and March
           | 25. The British Parliament formally adopted "Circumcision
           | dates" to come into agreement with the continent in 1751.

         | On the other hand, I did remember from school that January was

         | The Roman calendar started in January at least as far back as

         | are inconsistent as to who changed it, when it was changed, and
         | why it was changed. Also, most of our sources are writing well
         | after the change occurred (generally, they date to first
         | century AD). (This is why the Julian and Gregorian calendars
         | start on January 1, because the calendar they're based on did
         | as well! Although lots of European countries did decide for
         | much of the past 2000 years to start the year on other days
         | like December 25 or March 25 or Easter).
         | 
         | This gives me a vibe that a lot of the tradition of the Roman
         | calendar numbering is based on a "just-so" story that is made

         | actual evidence.

       | It's worth noting that the reason the calends had slipped so
       | badly is because it was Julius Caesar's job as pontifex maximus
       | to handle the periodic updates to the calends that kept it in
       | sync with the solar year. But he was too busy fighting in Gaul
       | and having his adventures to bother with it for years, so the
       | calendar slipped into chaos due to his mismanagement. He then
       | went on to fix his screw-up, but he didn't just decide to fix the
       | calendar, he was in a position where he'd screwed up so long he
       | had to fix it.
