Get Date based on day count in Java
calendar, date, java
Solution
Use Calendar for date arithmetic
Calendar c = Calendar.getInstance();
c.set(Calendar.YEAR, 2013);
c.set(Calendar.MONTH, Calendar.JANUARY);
c.set(Calendar.DATE, 1);
c.set(Calendar.HOUR, 0);
c.set(Calendar.MINUTE, 0);
c.set(Calendar.SECOND, 0);
c.set(Calendar.MILLISECOND, 0);
c.add(Calendar.DATE, numberOfDays);
Date date = c.getTime();
Note that the result may be different for different locales because of DST (summer time). The above example uses default locale.
Problem
Simple Question, but Google surprisingly had little on this. I have the `number of days` from Jan 1st of the year. How can I convert that to a `date` in Java?
