No. It should be "a year".
what do feel is an acceptable amount of days to be absent in a calendar year

There are generally 365 days in a year, but on a leap year, it's 366 days in a year. Actually no, there is 365.242199 to be exact, but a fraction i would say 365 1/4 days in a year.
Some can.
30 days. If u pass that, u can't even go to summer school
Both are acceptable.
ce n'est pas acceptable, c'est inacceptable
It is not quite as acceptable; however in ordinary speech it is fine to say it and most people won't mind.
I would say around 262 (leap year) & 261 (non-leap year). This is assuming that a year is about 365 Days. I hope that helps.
365 + 1/4 but just say 366in leap year
