Hello again Rupali,
I believe that you are passing the list of dates
as a dates option of the calendar. If this is the case then you will need to define your logic when and whether you want hightlight the dates. The aforementioned template will check whether the current date can be found the dates list (please note that dates list actually is list of milliseconds and that is why isArray works) and then depending on the current day (data.value) shows different icon. In order to acheive your goal you will need to implement the correct content template.
