Auto-populate every second day between two given dates

Question

I'm currently using the formula in this article to auto-populate a column of dates between to given dates:

=ArrayFormula(TO_DATE(row(indirect("A"&A2):indirect("A"&B2))))

How can I tweak the formula to give every second date? Column D in the article would then say:

• 01/04/2018
• 03/04/2018
• 05/04/2018
• 07/04/2018 ...and so on.

Answer 1

It seems like the formula skips a day if the start date is an odd date. Can this be corrected?

=ARRAYFORMULA(FILTER(TO_DATE(ROW(INDIRECT("A"&A2):INDIRECT("B"&B2))),
 MOD(ROW(INDIRECT("A1:A"&COUNTA(TO_DATE(ROW(INDIRECT("A"&A2):INDIRECT("B"&B2)))))), 2)))

Answer 2

=ARRAYFORMULA(FILTER(TO_DATE(ROW(INDIRECT("A"&A2):INDIRECT("B"&B2))),
               ISODD(TO_DATE(ROW(INDIRECT("A"&A2):INDIRECT("B"&B2))))))

---

=ARRAYFORMULA(FILTER(TO_DATE(ROW(INDIRECT("A"&A2):INDIRECT("B"&B2))),
              ISEVEN(TO_DATE(ROW(INDIRECT("A"&A2):INDIRECT("B"&B2))))))

Answer 3

=ARRAYFORMULA(FILTER(TO_DATE(ROW(INDIRECT("A"&A2):INDIRECT("B"&B2))),
                 MOD(TO_DATE(ROW(INDIRECT("A"&A2):INDIRECT("B"&B2))), 2)))
