I would like to auto enter consecutive dates on every other row in one column

Entering dates in Calc

  1. Drag the cell with date down.
  2. With a formula (If date is in A2):
    A3: =A2+1
    and drag or copy de formula down.
  3. Select the range to fill and use:
    Menu/Fill/Series, select Series data as Date and other options as you need.
