How to add Business hours to Date considering not adding weekends ? - Java

Question

I want to add certain number of hours to date, ignoring the weekends

For example,

(Friday 18:00) + 48 = (Tuseday 18:00) (Saturday and Sunday are ignored)

Answer 1

you need to handle it in custom way:

  public Date getTaskEndTime(Calendar startDate, int hours) {
        Calendar endTime = Calendar.getInstance();
        endTime.setTime(startDate.getTime());
        endTime.add(Calendar.HOUR, hours); // add 2 for saturday and sunday
        int dayOfWeek = endTime.get(Calendar.DAY_OF_WEEK);
        if (dayOfWeek == Calendar.SATURDAY) {
            endTime.add(Calendar.DATE, 2); // add 2 for saturday and sunday
        } else if (dayOfWeek == Calendar.SATURDAY) {
            endTime.add(Calendar.DATE, 1); // add 1 for sunday
        }
        return endTime.getTime();
    }
