Question

I can get the current date with the following code to show in DatePicker dialog for example.

    final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);

How can I show the actual date minus 18years (more or less 6570days)?

From my “research” I need to use DAY_OF_YEAR

Answer 1

Try using:

    c.add(Calendar.YEAR, -18);

You shouldn’t have to worry about the “more or less” of 6570 days since a Calendar object handles leap years (and exact number of days in a month itself).
