Not getting expected result from Enum

Question

enum DaysInMonth
    {
        Jan = 31, Feb = 28, Mar = 31, Apr = 30, May = 31, Jun = 30,
        Jul = 31, Aug = 31, Sep = 30, Oct = 31, Nov = 30, Dec = 31
    };
DaysInMonth dm = DaysInMonth.Dec;
        Console.WriteLine($"Number of days in {dm} is {dm:D}");

Getting Number of days in Jul is 31, expecting Number of days in Dec is 31

Its not a good idea to hardcode the number of days in a month. What about leap years?

The correct way to gets days in a month:

DateTime.DaysInMonth(year, month)

            Jul = 31, Aug = 31, Sep = 30, Oct = 31, Nov = 30, Dec = 31
        };



static void Main(string[] args)
        {
            DaysInMonth dm = DaysInMonth.Dec;
            Console.WriteLine("Number of days in {0} is {1} : ", dm, (int)dm);
