I need a calendar that shows the year for everyone, to avoid overlapping absences 🤷♀️
Hi Hilary,
I can't guess what you're imagining. ;-) What about to insert one column for each employee?

With just a few employees this is fairly manageable... with 10 employees this of course results in 12*(10+1) = 132 columns.
A visual inspection or representation in the form is not really compact. Therefore, most people use a horizontal or vertical calendar that shows a cell for each day and each employee. However, you don't want that resulting in 370 rows or columns because it looks bad printed on a piece of paper...
Make a draft yourself with manual colors and entries and show it to me. Then I can certainly help you automate this with formulas.
Andreas.
