I am running Plasma 5.12.5. The Digital Clock widget correctly displays the date in the system tray: 5/29/18. However, when I click it, the calendar is a day behind: May 28, 2018. I have checked both date and hwclock in konsole and they give the correct date. Searched for bug reports and did not find one. Any idea what might be going wrong with the calendar?

I've had the same issue for a few days now.

Running Arch Linux with all the latest updates. A colleague of mine has the same setup and is also experiencing the issue.

Experiencing the same issue here, I'm running Arch on three computers (a VM a laptop and a desktop) and they all have the same problem.

timedatectl and hwclock as both user and root display correctly. Date is incorrect in calendar, as well as in the extended PIM event calendar view. Changing to other timezones doesn't resolve the issue.

Qt 5.11 ?

Yes, Qt 5.11. So it is a bug then. Here is the Qt bug report from the notes in the patch on Phabricator:
