我的2个Android手机中的Calendar.WEEK_OF_YEAR不同

Question

I have this code

Calendar c = Calendar.getInstance();
c.set(Calendar.YEAR, year);
c.set(Calendar.MONTH, month - 1);
c.set(Calendar.DAY_OF_MONTH, 1);

When you get the c.get(Calendar.WEEK_OF_YEAR) it produce different week number

example c.set(2016, Calendar.JANUARY, 1);

one android phone produce c.get(Calendar.WEEK_OF_YEAR) = 1 and the other one is c.get(Calendar.WEEK_OF_YEAR) = 53
