Created attachment 136411 [details] Year 0 week view SUMMARY The difference between this bug report and the one I opened a little while ago, is that this time, you have to have "Astronomical Events" and "Holidays" turned OFF. The bug sure is interesting (nonsense.png). STEPS TO REPRODUCE 1. Scroll back to year 0 - 9 (from the decade view). 2. Click on year 10 (between year -1 and 1) OBSERVED RESULT The name of the year in the week view turns into Nan. Going into the week view utterly breaks everything. EXPECTED RESULT Show year 0 properly. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Linux 5.11.1, KDE Plasma 5.21.1 (available in About System) KDE Plasma Version: 5.21.1 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION I know I shouldn't be proposing solutions, but the 3 bug reports I opened could be fixed easily by not allowing the user to scroll past for example the 1900s.
