Diff 2 dates #4

Suppose I have 2 Jalali instances, how do I diff them in months? I suppose converting them back to DateTime and using difference method won't work, because there's no correlation between Jalali and Gregorian month diffs.

Hi, You can use a simple method like this:

int diff(Jalali j1, Jalali j2) {
    return (j1.year - j2.year)*12 + (j1.month - j2.month);
}
