\day \month \year
: Predefined counters
LaTeX defines counters for the day of the month (\day
,
1–31), month of the year (\month
, 1–12), and year
(\year
, Common Era). When TeX starts up, they are
set to the current values on the system where TeX is running. They
are not updated as the job progresses.
The related command \today
produces a string representing the
current day (see \today).
