I have implemented a method to get the date of the Monday in the current week, and I have assigned Monday to be the first day of the week.
But, no matter what I do,
try this :
public static Date getFirstDayOfWeekDate() {
Calendar cal = Calendar.getInstance();
cal.set(Calendar.DAY_OF_WEEK,
cal.getActualMinimum(Calendar.DAY_OF_WEEK));
Date now = new Date();
cal.setTime(now);
int week = cal.get(Calendar.DAY_OF_WEEK);
return new Date(now.getTime() - 24 * 60 * 60 * 1000 * (week - 1));
}
