Question

I am using java 1.7, How to find the quarter to which a particular date belong for a Fiscal year, which can start from 1st of any month (JAN-DEC) and also need the start date

Answer 1

Use a calendar:

Calendar cal = Calendar.getInstance();
cal.setTime(myDate);

Quarter:

int q = cal.get(Calendar.MONTH)%3;
System.out.println("Quarter: Q" + (q + 1));

Begining of quarter:

cal.set(Calendar.MONTH, 3*q);
cal.set(Calendar.DAY_OF_MONTH, 1);
Date start = cal.getTime();
System.out.println("Start: " + start);

End of quarter:

cal.add(Calendar.MONTH, 3);
cal.add(Calendar.DATE, -1);
Date end = cal.getTime();
System.out.println("End: " + end);
