<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">year chart</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for calendar that I've seen before include "list of appointments" , "Chart of times" , "Year chart" , "List of dates of land race" , "that's dated" .)
