How about combining the first two conditions into 1 ?

Code:
                if [ `expr $year % 100` -eq 0 -a `expr $year % 400` -eq 0 ]
                then
                        daysofmth=29
                elif [ `expr $year % 100` -ne 0 -a `expr $year % 4` -eq 0 ]
                then
                        daysofmth=29
                else
                        daysofmth=28
                fi

to
Code:
                if [ (($(($year % 100)) -eq 0 -a $(($year % 400)) -eq 0)) -o \
                (($(($year % 100)) -ne 0 -a $(($year % 4)) -eq 0)) ]
                then
                        daysofmth=29
                else
                        daysofmth=28
                fi

Haven't tested it tho'.

Aided by man sh

Code:
       ((expression))
              The expression is evaluated according  to  the  rules  described
              below  under ARITHMETIC EVALUATION.  If the value of the expres-
              sion is non-zero, the return status is 0; otherwise  the  return
              status is 1.  This is exactly equivalent to let "expression".
