formula for giving "yes" if services are between certain dates

Hello!

I have what i think might be quite a complicated formula question... I have 6 columns that represent certain services (3 services in total) and dates on which they were taken up (see attached document). I would like the result of the formula to be "yes" if either of the 3 services have been given within certain date parameters (i.e. within the quarters specified in the green box also on the spreadsheet). Does anyone have any idea how this oculd be done?

I have kind of been doing similar things using a SUMPRODUCT function but I don't want this to actually count up the number of services, i just want the formula to say "yes" if any of the 3 dates are within a specific time frame.....thinking about it the services columns could just be completely ignored and the 3 date columns could be the only things used in the formula.....

Any ideas?
