         | There is actually no hard evidence that the Romans ever started
         | their calendar in March instead of January. The earliest
         | contemporaneous use of the calendar relies on January 1 as the
         | start of the year, short February, and with intercalation
         | happening after (or maybe within) February.
         | 
         | The primary evidence we use to indicate that the start of the
         | year shifted is... the apparently wrong month names. Some
         | writers did describe a calendar that starts at March and ends
         | in December, with winter basically having no proper calendar--
         | but these are writers describing how their calendar worked
         | several centuries ago, attributing it to mythological figures,
         | and the explanation strikes me as very heavily a "just so"
         | explanation.
         | 
         | If you want my hypothesis, the Roman civil year never started
         | in March. But March would have had some amount of primacy, as
         | it indicates the start of the _planting_ year. Shenanigans in
         | the calendar would have occurred in February to ensure that the
         | equinox is properly timed to happen in March. But the civil
         | year would have started closer to the beginning of winter for
         | other reasons (perhaps taxation? but finding this level of
         | granularity of information on Roman taxation is difficult).
         | 
         | In this hypothesis, the month names were not incorrect because
         | they were never intended to count from the beginning of the
         | year. Note that the first 6 months of the civil year have
         | names, while the last 6 are merely numbered. It makes no sense
         | to me that you'd make up special names for the first 4 and the
         | last 2 months of the year, while skipping everything in the
         | middle.

         | other is more common. Most of the Slavic languages, and
         | Chinese, among others, use indexed from Monday = 1.
         | 
         | Then there's Swahili: Saturday = 1 and Friday = 7. Though
         | personally, I believe Sunday is the 0th day of the week.
