Image of Calendar plasmoid displaying previous day's date.

The Calendar plasmoid widget displays the previous day's date.

To reproduce, click the Digital Clock or the Analog clock to display the calendar widget, or add the calendar widget to the desktop.

The Digital Clock plasmoid, "Adjust the date and time...", date in bash, and timedatectl all display the correct date. It is just the graphical calendar widget that has the issue.

I have 3 PCs all run KDE Neon, 3 use Xorg and 1 laptop that uses Wayland and they all exhibit the bug. Actually, my 9 year old daughter, Elizabeth showed me the bug on her PC. All computers are fully up to date with Neon repos as of this writing.

KDE Plasma = 5.13.1
Frameworks = 5.47.0
QT = 5.11.0

This could be a duplicate of Bug 395464 submitted on 6-15, which would make sense due to his description of the date being stuck on the 14th. I wanted to include more detail and submit a screenshot, so I created a new ticket. I hope that is okay.
