I managed to hide other month days using the css below. Anything I should be worried about doing it this way? it seems to be fine so far. 

.k-calendar .k-other-month{
        visibility: hidden;
    }

My last gripe with this is that the month is clickable to open the date selector, anyway I can disable that?

Thank you Marin, I managed to color the days with event as you mentioned, and hide the navigation. The problem is I am trying to create a calendar like the yearly scheduler. Therefore with the multiple calendars in proximity to each other, with dates from other months, results in displaying the event in both calendars on some days. Which seems like it would be very confusing for the users. 

Is it possible to at least add the option for us to hide the dates from other months, like the following

The ShowOtherMonthDays property controls whether the day matrix includes the last days of the previous month and the first days of the next month when they fall on the same week as the first or last day of the month.

Hi Marin,

Thank you for the prompt answer, I will try the method you mentioned.

It wouldn't have any trouble with multiple events on same day correct?

Also is there a way to remove the navigation part of the calendar? 

Lastly when I used the code mentioned here (month cell template) to do a quick test, it showed the previous and next month dates. How can I make it like example and hide the days of other months.
