I am using dhtmlxCalendar.I am using date format as DD-MON-YYYY for ex-10-FEB-2009.I have to give validation based on this format such that startDate must be less than end date.

I have tried through this approach:



confirm(“start date must be less than end date”);


it giving me values as “NaN”.

Please update me how to give date validation in DD-MON-YYYY format


There is getDate() method is returns selected date in teh calendar.

var date = cal.getDate();

Then you can apply any formating to this value:

var str = cal.getFormatedDate(dateformat, date);
