Hey @paul2009, it appears the code worked for December 2023, March 2024, and November 2024, however there's issues every other month. The issues are always on the Tuesdays, Wednesdays, Thursdays, and even the Fridays in June 2024.
Even though there are only 7 columns, I tried adding .yui3-calendar-day.calendar_col8 to see what would happen, and it would appear in different columns each month.
How can I fix this?
