Which requirements does my method not meet? The only month that changes its number of days is February, so the procedure simply calculates that, based upon the year.
The draggable blocks are there so others can drag them into their projects, this is a community thing, nothing to do with the content.
As I said, what I offered is simply "another method", doesn't stop anyone using yours.
I also note, having tested your method, that it does not report the days in months correctly for 1700, 1800, 1900, 2100, 2200, 2300, none of which were leap years. (ref)
Maybe I need an award ?
