Hii Aleksandar

Here is the link to the issue, hope they will work on it, something easy and must be on any calendar ui,  wheather you like it or not , to be success you must look what others do, what is trending right now etc, if you go p-calendar from primefaces u can see what I mean, car is a car but a car without a break is not a car is something else
