table of tables that hold pattern and other information used to extract date parts for translation and reconstruction
Tables have the form:
[1] - pattern for a particular date format; must include captures for the requiste date components:
day, month, year which ever are included in the date format
[2] - a letter 'd', 'm', or 'y' that identified the content of the first (left-most) capture
[3] - same as [2] for the second capture
[4] - same as [2] for the last (right-most) capture
ymd numeric dates have no hames so are not translated; use |df= parameter in the cs1|2 template for that.

February, April, June, September, or October lang_obj:formatDate() will return the 'next' month.
