public static double clockAngle(int hours, int minutes)
    {
        double minuteAngle = minutes * 6;
        double hourAngle = hours * 30 + minutes / 2.0;
        double result = hourAngle - minuteAngle;
        if (result < 0)
        {
            result += 360;
        }
        return result;
    }
