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.
