why do I get wrong month when parsing with java calendar

Question

Date fakeDate = sdf.parse("15/07/2013 11:00 AM");
Calendar calendar = Calendar.getInstance()
calendar.setTime(fakeDate);
int currentMonth = calendar.get(Calendar.MONTH);

I get currentMonth == 6 instead of 7.

why is that?

While the question has been answered, the good solution is to drop the outdated `Calendar` class and use [java.time, the modern Java date and time API](https://docs.oracle.com/javase/tutorial/datetime/), instead. It is so much nicer to work with, and it numbers months the same way humans do. — Ole V.V., Mar 11 '18 at 06:59

Because Calendar.MONTH is ZERO based. Why?

Check the docs: (always)

Field number for get and set indicating the month. This is a calendar-specific value. The first month of the year in the Gregorian and Julian calendars is JANUARY which is 0; the last depends on the number of months in a year.

As the doc says - Field number for get and set indicating the month. This is a calendar-specific value. The first month of the year in the Gregorian and Julian calendars is JANUARY which is 0; the last depends on the number of months in a year.

So try something like this

int currentMonth = calendar.get(Calendar.MONTH)+1;

Because calendar.get(Calendar.MONTH) shall give you (currentMonthValue-1) as the value of january starts with 0

It should be

int currentMonth = calendar.get(Calendar.MONTH)+1;
