 Two tables, one called tblOffice the other called tblFactory.

Both tables have the following fields.  FirstName, LastName, Birthday

I need to combine (join) both tables where the Birthday = today's date.

      DIM vDate       
      vDate       = Date()  

      vSQL = "" 
      vSQL = vSQL & " SELECT o.FirstName, o.LastName, 0.Birthday, f.FirstName,  f.LastName, f.Birthday  "
      vSQL = vSQL & " FROM tblOffice o "
      vSQL = vSQL & " CROSS JOIN tblFactory f "      
      vSQL = vSQL & " WHERE o.Birthday  = '" & vDate & "' OR  f.Birthday  = '" & vDate & "' "

Cross join does not appear to be producing the correct results.

Try something along the lines of:
SELECT o.FirstName, o.LastName, o.Birthday
FROM   tblOffice o
WHERE  o.Birthday = vDate
UNION
SELECT f.FirstName, f.LastName, f.Birthday
FROM   tblFactory f
WHERE  f.Birthday = vDate
