How to display the week number in a SharePoint calendar

  • You can certainly do something like this with script in the page. I think the tricky bits will be:
    * Figuring out what the week *is*, i.e., you’ll have to grab the current month info and the Sunday date from the DOM for at least the first week of the month.
    * Calculating the week number based on that date.
    * Figuring out where in the DOM to put the week numbers.


  • I updated the original post with a screenshot (see update 1)

  • Actually, the DatePicker and the Monthly Calendar view are totally different beasties and have different behavior and markup. If you want to display the week number in the Monthly Calendar view, you’ll need to develop the script from scratch.
