Days on a calendar as watermark/background so events can be overto

[Guest]

I've created a calendar using a table. I'd like the dates on the calendar to
be a watermark or background image, so that the events I put on the calendar
can be typed overtop of the date.

One option would be to put your dates in text boxes in each cell with any
special formatting (font, color, etc.), then Format >Text box and on the
Layout tab select Behind text.
