Retun greatest # of cells between nonzero
Try this array formula** :
=MAX(FREQUENCY(IF(A2:X2=0,COLUMN(A2:X2)),IF(A2:X2< 0,COLUMN(A2:X2))))
Note that empty cells will be evaluated as 0.
** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER)

OK, I think I've seen this before, but I can't recall how it's done. So,
if I
have a table with dates as headers, and a particular row may have, say:
0 0 0 1 0 0 0 0 0 0 2 0 0 1 0 0 0 4 0 0 0 0 0 1
As individual values.
I would like a formula that tells me that the longest time frame between
non-zero fields was 6 days. The actual value of the nonzero cells can
vary.
