How to increase the font size of the date that is selected on a CalendarDatePicker

I have a CalendarDatePicker control on my UWP app. I am not able to increase the size of the font of the date that is selected using the FontSize attribute.

How can I easily do this without overriding a lot of styles?

Here is the basic code I have:

<Page
    x:Class="CalendarPickerExample.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:CalendarPickerExample"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <CalendarDatePicker FontSize="30" />
    </Grid>

</Page>

No matter what size I set the FontSize attribute on the CalendarDatePicker, the size of the font of the selected date does not increase.

You can use the Visual Tree Extensions from the UWP Community Toolkit to grab the textbox control by name or type and modify its FontSize property:

 <CalendarDatePicker x:Name="Calender"/>

-

 Calender.FindDescendantByName("DateText").FontSize = 30;

You can check the properties of the control using Live Visual Tree tool, in your case you want to change the size of the internal TextBlock:

Live Visual Tree Live Property Explorer

You can modify the TextBlock font size in a copy of the default style https://msdn.microsoft.com/en-us/library/windows/apps/mt299110.aspx

As you can see, it is hardcoded to 15 in the default template:

<TextBlock x:Name="DateText"
                   HorizontalAlignment="Left"
                   Foreground="{ThemeResource SystemControlForegroundBaseMediumBrush}"
                   Text="{TemplateBinding PlaceholderText}"
                   Grid.Row="1"
                   FontSize="15"
                   Padding="12, 0, 0, 2"
                   VerticalAlignment="Center" />
