ASP.NET Month Calendar
When simply selecting the date is not enough, give your users a richly adaptable calendar with localization support, multiple selection, and flexible date navigation by mouse or keyboard.
Navigation
Keyboard and mouse navigation schemes similar to Windows 7 make the control accessible as it employs a familiar calendar interaction framework.
Range Selection
Multiple dates selection and week number displays make it easier for range selection of dates.
Localization
Full localization support of month and day texts are ideal for applications that must be supported internationally.
