[net.puzzle] A calendar puzzle

Perusing my calendar for this year, I noticed that it follows
a common convention of alloting space for the days of each
month in a 5x7 matrix.  Those occasional months that span
6 weeks have the cells for days 23 and 30, and 24 and 31 if
applicable, combined so that every month fits in 5 rows.

This brought to mind a fairly simple puzzle:  For calendars designed
as above, what is the greatest number of months that might have to
have two or more dates combined in a single cell?  The least number?
The expected number?  For what year will the next calendar with the
greatest number occur?

Please don't bother posting your solution to the net or to me.
It's a curiosity easily solved (though the last question is a little
tricky); I just found it amusing.  I'll post the answers in a few
days.
