Abstract
This code snippet adds a certain number of days to a date excluding the weekends. By default, when you add a certain number of days to a date the weekends are included. To exclude them, you can use this snippet.
Logic
- Fetch the number of days to be added and first add whole weeks (of 5 work days)
- Run a loop to add a day each until the number of remaining days - Skip if the day is a "Saturday" or a "Sunday"
- After adding the days, skip the end if it is a weekend
- Clear the time and return the date

Date date(Date from, int nod){
Calendar c1 = GregorianCalendar.getInstance();
c1.setTime(from);
int weeks = nod/5;
int remDays = nod%5;
//Adding whole weeks
c1.add(Calendar.WEEK_OF_YEAR, weeks);
//Run a loop and check each day to skip a weekend
for(int i=1;i<=remDays;i++){
c1.add(Calendar.DAY_OF_MONTH, 1);
if (c1.get(Calendar.DAY_OF_WEEK) == Calendar.SATURDAY)
c1.add(Calendar.DAY_OF_MONTH, 1);
if (c1.get(Calendar.DAY_OF_WEEK) == Calendar.SUNDAY)
c1.add(Calendar.DAY_OF_MONTH, 1);
}
//Skip ending weekend
if (c1.get(Calendar.DAY_OF_WEEK) == Calendar.SATURDAY)
c1.add(Calendar.DAY_OF_MONTH, 1);
if (c1.get(Calendar.DAY_OF_WEEK) == Calendar.SUNDAY)
c1.add(Calendar.DAY_OF_MONTH, 1);
//move to 0:00
c1.clearTime();
return c1.getTime();
}
