How to calculate 2nd Friday of Month in C# [duplicate]

Answer 1

I would go for something like this.

    public static DateTime SecondFriday(DateTime currentMonth)
    {
        var day = new DateTime(currentMonth.Year, currentMonth.Month, 1);
        day = FindNext(DayOfWeek.Friday, day);
        day = FindNext(DayOfWeek.Friday, day.AddDays(1));
        return day;
    }

    private static DateTime FindNext(DayOfWeek dayOfWeek, DateTime after)
    {
        DateTime day = after;
        while (day.DayOfWeek != dayOfWeek) day = day.AddDays(1);
        return day;
    }
