Navigating multiple calendars in SharePoint

This topic came up over on SharePoint.StackExchange.com, and I thought I’d share here too.

You may want to setup a single page to view multiple calendars. Calendar overlay is a great way to handle this, but what if you want to see these side by side, and let the user navigate the dates in unison, so clicking Next Day will go to the next day, on each calendar.

Looking at the above, clicking the day navigation will only update that one calendar web part. Not cool. How do we fix that?

Insert a Snippet App Part, and copy and paste this code into it. It’s a little raw, but it works. Class it up for your brand and site as you need.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<div>
<a href='#' id='newPrevDay'>Previous Day</a>  
<a href='#' id='newNextDay'>Next Day</a>
</div>

<script type="text/javascript">
$(document).ready(function(){

ExecuteOrDelayUntilScriptLoaded(overrideButtons,"SP.UI.ApplicationPages.Calendar.js");

function overrideButtons() {
$("#newPrevDay").click(function() {
$("a[title=\"Previous Day\"]").each(function() {
eval($(this).attr("href"));
});
});

$("#newNextDay").click(function() {
$("a[title=\"Next Day\"]").each(function() {
eval($(this).attr("href"));
});
});
}
});
</script>

Once the code is in, the calendar’s buttons will be hidden and the new buttons will appear, like so:
