start_date, days, and holidays are named ranged here.

It is an arary formula so commit with Ctrl-Shift-Enter

Your formula is handy, but will give a REF error if days6553. I believe that
is because the ROW(INDIRECT("1: ...) gives a result of greater than 65536 for
the second factor, which would result in an invalid cell reference.
