I have a schedule component showing the TimelineYear view.
I have created a cellTemplate that colors all weekend days with a different color.
For months, that do not begin or end at start or end of the row, invalid colorings can be shown.
The cellTemplate is called multiple times with the same date, so within it I cannot distinguish if it is a "real" date, or a date from a previous month.
See e.g. the month of may. The cellTemplate is called 6 times with a date of 05/01/2021.
The cells before the correct 05/01 cell are marked as "e-other-month" in css, but I cannot access that within the template function.
