How do I get the quarter of a given Date?

Given a java.util.Date object how do I go about finding what Quarter it's in?

Assuming Q1 = Jan Feb Mar, Q2 = Apr, May, Jun, etc.

Solution

  • Since Java 8, the quarter is accessible as a field using classes in the java.time package.

    import java.time.LocalDate;
import java.time.temporal.IsoFields;

LocalDate myLocal = LocalDate.now();
int quarter = myLocal.get(IsoFields.QUARTER_OF_YEAR);

    In older versions of Java, you could use:

    import java.util.Date;

Date myDate = new Date();
int quarter = (myDate.getMonth() / 3) + 1;

    Be warned, though that getMonth was deprecated early on:

    As of JDK version 1.1, replaced by Calendar.get(Calendar.MONTH).

    Instead you could use a Calendar object like this:

    import java.util.Calendar;
import java.util.GregorianCalendar;

Calendar myCal = new GregorianCalendar();
int quarter = (myCal.get(Calendar.MONTH) / 3) + 1;
