B - PROBLEMS :
To leverage on default SharePoint features, we need to customise the CSS style sheet.
C - SOLUTION:
1. Go to Site Settings to change the Regional Settings so that Mons are the first days in the calendar view.
2. Embed a Content Editor webpart into the page so that it can host the below CSS style.
D - SOURCE CODE:
<style type="text/css">
table.ms-acal-month > tbody > tr > td:nth-of-type(6) > div {
background-color:#ebebeb;
position:relative;
z-index:999;
}
table.ms-acal-month > tbody > tr > td:nth-of-type(7) > div {
background-color:#ebebeb;
position:relative;
z-index:999;
}
</style>
