formulae to look at 52 sheets &count if 2 cells have data entered

Hi All

Been a busy boy today, on excel. Im wondering if any one could assist me in this formuleas I am struggling with?

Ok here it goes...

I would like the formulae to look at 52 sheets, specifically 2 cells within the sheet, if they have dates entered into them, return a 1.

E.g.

Sheet 1

Cells N12&012 have dates in them = 1

sheet 2

Cells N12 has a date in it but o12 has not return = 0

etc etc

Hope this makes sense

Your help would be much appreciated.

Thanks

Andrew
