Create a custom attribute.

public class CheckDateRangeAttribute: ValidationAttribute {
    protected override ValidationResult IsValid(object value, ValidationContext validationContext) {
        DateTime dt = (DateTime)value;
        if (dt >= DateTime.UtcNow) {
            return ValidationResult.Success;
        }

        return new ValidationResult(ErrorMessage ?? "Make sure your date is >= than today");
    }

}

code was written off the cuff so fix any errors :)
