Here is my configuration:

$('.date').datepicker('option', $.datepicker.regional[gdml.culture.getCulture()]);

$('.date').datepicker({

changeYear: true,

changeMonth: true,

yearRange: 'c-100:c+100',

dateFormat: gdml.culture.getDateFormat(),

minDate: new Date(1900, 01, 01),

maxDate: '+0d'

});

I'm using the DatePicker with French locale.

Picking random dates invalidates sometimes.

For example, 08/16/1920 is not valid but 08/24/1920 is ???

This is extremely random with no specific date giving issues.

getDateFormat comes from custom code:

var gdml = gdml || { };

gdml.culture = function () {

var cultureName = "",

setCulture = function (name) {

cultureName = name;

},

getCulture = function () {

return cultureName;

},

isFrenchLocale = function () {

return cultureName.toLowerCase() == "fr";

},

isEnglishLocale = function () {

return !isFrenchLocale();

},

dateFormat = 'mm/dd/yy',

getDateFormat = function () {

return dateFormat;

},

setDateFormat = function (value) {

dateFormat = value;

};

return {

setCulture: setCulture,

getCulture: getCulture,

isFrenchLocale: isFrenchLocale,

isEnglishLocale: isEnglishLocale,

getDateFormat: getDateFormat,

setDateFormat: setDateFormat

};

} ();
