One of the annoying tihings in Java is data handling. Here is a method to find the number of days between 2 calendar dates, ignoring weekends.

Need to set these 2 variables. I have cut this from another class. I may at some point update this to have a generic example, but you should have enough to get by with on this.

Calendar todaysCalendar;

Calendar laterCalendar ;

long MILLSECS_PER_DAY = 1000 * 60 * 60 * 24;

// Find number of calendar days between now and then. All in same
// timezone and we are only using dates not times so this can be done
// this way

        long endL = laterCalendar.getTimeInMillis()
                + laterCalendar.getTimeZone().getOffset(
                        laterCalendar.getTimeInMillis());
        long startL = todaysCalendar.getTimeInMillis()
                + todaysCalendar.getTimeZone().getOffset(
                        todaysCalendar.getTimeInMillis());
        long deltaDays = (endL - startL) / MILLISECS_PER_DAY;

// now remove weekends
// First remove complete weeks
int weekdays = 5 * ((int) deltaDays / 7);

// Now its as if we have less than one week between the days
int leftover = (int) ((deltaDays) % 7);
if (leftover > 0) {
int fromday = todaysCalendar.get(Calendar.DAY_OF_WEEK);
int move = fromday + leftover;

if (move > 7) {
leftover -= 2;
}
weekdays += leftover;
}
