+packages have filled this gap.  This package fills it, as well, with a pure
+TeX-primitive implementation.  It can print dates, advance them by numbers of
+days, weeks, or months, determine the weekday automatically, and print them
+in (mostly) arbitrary format.  It can also print calendars (monthly and
+yearly) automatically, and can be easily localized for non-English
+languages.")
