% Overly complicated steps to obtain this Sunday's date:
    \newcount\dayofweek % create some "counters" to do simple math
    \newcount\diff
    \dayofweek=\thedatedayname\relax % gives timer the value of day of week (1-7)
    \diff=7\relax % we will be subtracting the current day of week from 7
    \advance\diff-\dayofweek % this produces the number of days between now and Sunday
    \setdatetoday
    \addtocounter{datenumber}{\diff} % that way we can increment the counter of datenumber by the number of days between now and Sunday
    \setdatebynumber{\thedatenumber} % to bring us to the date of the next Sunday
    % Now \datedate will produce the date of the next Sunday
% End Obtaining this Sunday's date
