Calc: LANDSCAPE Prnt... how How Drag Dates dwn,ONLY incremntng MONTH?

HP Pavilion, Win 10
Hilitng 3 cells… dragng - doesn’t work. ?

PS: Ho w increase FONT size on THIS sheet?

Enter two dates that differ by one month into subsequent cells, then select both cells and then pull down.

To apply different font settings best create a new style derived from the Default style (to inherit all default settings) and adjust font settings to your needs, then select the area (or in this case maybe the entire sheet with Ctrl+A) and apply the newly created style.

And best please only one question per question…
