Chronograph dating

The date being in chronogram means that the I,V,X,L,C,D and M letters in the legend are all Roman Numerals unless further mentioned, and if added together, total the date.

When legend has a chronograph date in it, if the page has description of the legend, the Roman Numerals that are to be added up should be in bold, then a {_+_+_+ ect} written in the unabridged legend line of those Roman Numerals being added up, lastly the sum which will be the date will be in {_ _ _ _} at the end of the translated legend line.
