Forgot to mention.  Umbraco 7 using Razor (not MVC).

Thanks Allan,

Super easy when you know how.

Here is the actual final code I created, works fine for me (razor umbraco 7 - not MVC but easilly converted I suspect).  It is a filter for date picker, so you can effectively have a calendar sorted/split by month.

@* Load dates for start and end of current month *@

DateTime StartDate1 = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1);

DateTime EndDate1 = StartDate1.AddMonths(1).AddDays(0);

var dback = "";

var dforw = "";

int dmovt = 0;

int cn;

@*Check querystring for date navigation +/- x months and pre links for next navigation*@

if (Request.QueryString["cn"] != null) {

int.TryParse(Request.QueryString["cn"], out cn);

StartDate1 = StartDate1.AddMonths(cn);

EndDate1 = EndDate1.AddMonths(cn);

dmovt = cn-1;

dback = "?cn="+dmovt.ToString();

dmovt = cn+1;

dforw = "?cn="+dmovt.ToString();

} else {

cn = 0;

dback = "?cn=-1";

dforw = "?cn=1";

}

@* Navigation and title at top of page *@

@:<div class="eventsHead">

@:<div class="CalNavRight"><a href="@dback" title="Previous month"><img src="/Theme/images/global/Arrow-Left-S.png" title="Previous month" /></a> @umbraco.library.FormatDateTime(StartDate, "MMMM") <a href="@dforw" title="Next month"><img src="/Theme/images/global/Arrow-Right-S.png" title="Next month" /></a></div>

@:<h1>@Model.pageTitle</h1>

@:</div>

@* initial prep for multi events on 1 day *@

@:<div><div><div>

@* pull all events from tree filtered by date params already set (for 1 month) *@ 

foreach (dynamic eventItem in node.Descendants().Where("eventStart > @0 && eventStart < @1 && nodeTypeAlias.Contains(\"Event\")", StartDate1, EndDate1).OrderBy("eventStart")) {

@* Check if event is ont he same day as the last, if so maintain the div *@

if (olddate.ToString() == eventItem.eventStart.ToString("ddMMyy")) {

@:<div class="events">

@:<a href="@eventItem.Url" class="" title="more about @eventItem.eventTtle">@eventItem.eventTtle @Xloc</a>

@:</div>

} else {

@* Creat new div for new date *@

@:</div></div></div>

@:<div class="EventCont">

@:<div class="eventDay" style="border: 2px solid @bgcolour;" >

@:<div class="eventInner">

@:<div class="eventTitle" style="background-color: @bgcolour;"><h2 class="tile event">@eventItem.eventStart.ToString("ddd d MMMM")</h2>

@:</div>

@:<div class="events">

@:<a href="@eventItem.Url" class="" title="more about @eventItem.eventTtle">@eventItem.eventTtle @Xloc</a>

@:</div>

}

olddate = eventItem.eventStart.ToString("ddMMyy");

}

@* Close final date container div *@

@:</div></div></div>

Hi Stephen

Happy that you found it useful. I used this reference by the way. http://our.umbraco.org/documentation/Reference/Querying/DynamicNode/
=>Collections

Btw. you probably write macroScripts, so you can use a tidier syntax switching between razor and html. Like:

@{
 if (olddate.ToString() == eventItem.eventStart.ToString("ddMMyy")) 
 {
   <div class="events">
    <a href="@eventItem.Url" class="" title="more about @eventItem.eventTtle">@eventItem.eventTtle @Xloc</a>
   </div>
 } 
 else ...

}

is working on a reply...
