Month view split day Morning/Afternoon

Unfortunately this is not supported at the moment.

any update ?

I have managed to do this with a slight hack. If you set the business start and end hours and the cell duration you can split the day into morning and afternoon.

BusinessBeginsHour = 9,
BusinessEndsHour = 18,
CellDuration = 240,

This will give you something that looks like:

12 | 16 | 12 | 16

but you can then use JQuery to find these values and replace them with your morning and afternoon text

$("[title='16 '] > div").text("Afternoon")

In the Month control (http://doc.daypilot.org/month/) splitting the cell into two parts would be possible using BeforeCellRender by inserting custom <div> elements. That would split the day cell into two parts visually but it won't affect the event placement (they will be stacked just like before).

In the Scheduler, it's possible to customize the cell size using CellDuration (as Graham suggests) and the time header using OnBeforeTimeHeaderRender:
