Validate specific date format in C#

The following string needs to be validated: "04-01-2021 00:00:00 +00:00".

I've got the following method that checks if a string is a valid date, although it returns false for this string.

        private static bool IsValidDate(string value)
        {
            var allowedFormats = new[]
            {
                "yyyy-MM-dd", "yyyy-MM-ddThh:mm:ss", "yyyy-MM-dd HH:mm:ss",
                "dd-MM-yyyy", "dd-MM-yyyyTHH:mm:ss", "dd-MM-yyyy HH:mm:ss"
            };
            var cultureInfo = new CultureInfo("en-GB");

            return DateTime.TryParseExact(value, allowedFormats, cultureInfo, 
                DateTimeStyles.AllowWhiteSpaces, out _);
        }

Is there anything I'm missing from the allowedFormats?

Thanks!

It will work with "dd-MM-yyyy HH:mm:ss zzzzz" format string.

zzzzz part stands for offset (+00:00) in your string.

Check out the Microsoft's documentation.
