DESCRIPTION
The Vietnamese Lunar Calendar (introduced in Plasma 6.7) displays incorrect
lunar dates compared to the actual and official Vietnamese lunar calendar. This
discrepancy can cause significant confusion for users relying on it for
traditional events.
STEPS TO REPRODUCE
1. Add the Digital Clock / Calendar widget to the panel.
2. Enable the Vietnamese Lunar Calendar alternate calendar option in the widget
settings.
3. Open the calendar and compare the lunar dates with the standard Vietnamese
lunar calendar.
OBSERVED RESULT
The lunar dates shown in the Plasma calendar widget are incorrect. I have
confirmed this discrepancy by cross-checking with a standard smartphone
calendar. (Please see the attached screenshot comparing the widget and a
correct calendar website).
EXPECTED RESULT
The lunar dates should accurately match the official Vietnamese lunar calendar
(e.g., as shown on reference sites like https://www.xemlicham.com/ and standard
mobile devices).

ADDITIONAL INFORMATION
