#!/bin/sh

MONTH=`date +%m`
DAY=`date +%d`

case "$MONTH" in
    2)
        DAYS=28
        ;;
    4|6|9|11)
	DAYS=30
	;;
    1|3|5|7|8|10|12)
	DAYS=31
	;;
esac

if [ $DAYS = $DAY ]; then
    echo "Last day of Month"
else
    echo "$((DAYS-DAY)) days until next month"
fi

However, this script does not look if we have a leap year.

     Ciao,
