In the calendar view we have different kind of categories so based on selected category we have applied different color coding in calendar view using JavaScript.

$(window).bind("load", function() {
   // code here
    ColorCalendar();
//This will help to previous or next month calendar
    $('a[title="Previous Month"]').bind('click', function (event) {
        setTimeout(function () {
            //do what you need here          
            ColorCalendar();
        }, 1000);
     
    });
    $('a[title="Next Month"]').bind('click', function (event) {
        setTimeout(function () {
            //do what you need here          
            ColorCalendar();
        }, 1000);

    });
});

function ColorCalendar() {

var arrayofDivItems = $('div[class="ms-acal-item"] a');
$('div[class="ms-acal-item"] a').each(function(i) {

var colour = GetColourCodeFromCategory(this.text);
if(this.parentNode.parentNode.parentNode.className == 'ms-acal-item')
{
this.parentNode.parentNode.parentNode.style.backgroundColor = colour;
}
else if(this.parentNode.parentNode.className == 'ms-acal-item')
{
this.parentNode.parentNode.style.backgroundColor = colour;
}
else if(this.parentNode.className == 'ms-acal-item')
{
this.parentNode.style.backgroundColor = colour;
}

});
}

function GetColourCodeFromCategory(category) {
var colour = null;
switch (category.trim().toLowerCase()) {
case 'leave':
