Use the pareseLocale function to create an object of type Date from a string. If you provide no custom formats, this function uses the Sys.CultureInfo.CurrentCulture property to determine the culture value.
To create a date from a locale-specific string that uses the current culture, set the EnableScriptGlobalization()()() property of the ScriptManager control to true. You must also modify settings in the Web.config file so that the culture attribute of the globalization section is set to auto.
