Is it possible to use [Range] annotation for dates?
something like
[Range(typeof(DateTime), DateTime.MinValue.ToString(), DateTime.Today.ToString())]

The range attribute allows a numeric range to be specified for a slot when a numeric value is used in that slot. If a numeric value is not used in that slot, then no checking is performed.
Data annotations (available as part of the System. ComponentModel. DataAnnotations namespace) are attributes that can be applied to classes or class members to specify the relationship between classes, describe how the data is to be displayed in the UI, and specify validation rules.
We'll use the following Data Annotation attributes: Required – Indicates that the property is a required field. DisplayName – Defines the text to use on form fields and validation messages. StringLength – Defines a maximum length for a string field. Range – Gives a maximum and minimum value for a numeric field.
ComponentModel. DataAnnotations Namespace. Provides attribute classes that are used to define metadata for ASP.NET MVC and ASP.NET data controls.
I did this to fix your problem
public class DateAttribute : RangeAttribute { public DateAttribute() : base(typeof(DateTime), DateTime.Now.AddYears(-20).ToShortDateString(), DateTime.Now.AddYears(2).ToShortDateString()) { } } Docs on MSDN says you can use the RangeAttribute
[Range(typeof(DateTime), "1/2/2004", "3/4/2004",
ErrorMessage = "Value for {0} must be between {1} and {2}")]
public datetime Something { get; set;}
