Two small things I would love to see changed with the current calendar, but will never happen:
* February deserves to have more days, so that every month has either 30 or 31 days. Taking away 1 day from August and January, and giving them to Feb would do it. In leap years, Feb can have 31 days.
* The year ought to start on March 1st. So that September regains its place as the 7th month, October the 8th month, November the 9th month, and December the 10th month. Because that's what "Sept", "Oct", "Nov", and "Dec" mean.
In addition to making the number months make sense again, it would also make leap day at the end of the year (again), which probably also makes more sense.
I think your point about February is probably good, but I don't know that pushing two changes is possible.
> Because that's what "Sept", "Oct", "Nov", and "Dec" mean.
Please keep that idea to whatever languages that assign those names to months. East Asian languages have been calling them literally "month 1/2/3/etc." without problems, just like how most languages don't have 31 different words for each day in a month.
Alternatively, if we have to give months aliases, why not fix those languages by e.g. reassigning "September" to the 7th month?
