You probably need to define a StringTemplateShows instance for
Data.Time.Day, and then use stShowsToSE to define a ToSElem instance.
Something like
instance StringTemplateShows Day
where stringTemplateFormattedShow formatString = formatTime defaultTimeLocale
formatString
{- or whatever -- I'm not sure what the correct time-formatting function is
-}
instance ToSElem Day
where toSElem = stShowsToSE
