While I suggested using ":1m$" elsewhere in the thread, I'm glad I'm
not the only one doing something similar with man-pages.

However, I've used calendar programs to do this. You can either use
the venerable calendar(1) format:

# BSD date(1)
$ d=$(date +%s); while read line ; do printf '%s\t%s\n' $(date
-r $d +%Y-%m-%d ) "$line" ; d=$(( $d + (60*60*24) )); done <
list_of_manpages.txt >> ~/.calendar

# Linux date(1)
$ d=$(date +%s) ; while read line ; do printf '%s\t%s\n'
$(date --date="@$d" +%Y-%m-%d) "$line" ; d=$(( $d + (60*60*24) )) ;
done < list_of_manpages.txt >> ~/.calendar

(though beware that, if you have more than 365 entries, calendar(1)
seems to ignore the year)

You can then invoke

$ calendar

(or put it in a cron-job if it's not automatically picked up by your
system scripts)

I do something similar using remind(1) which I prefer for calendaring:

$ cat remify_manpages.awk
BEGIN {
print "SET ManStart date(2020,1,5)"
}
$7 ~ /^[1678]$/ {
printf("REM [ManStart + %i] MSG man %s %%\"%s%%\"%%\n", NR - 1, $7,
$6)
}

$ find /usr/share/man/man[1678]/ -maxdepth 2 -type f |
grep -vi perl |
sort -R |
awk -F'[./]' -f remify_manpages.awk > manpages.rem

(I ignore the perl man-pages and randomly shuffle them)

and then invoking remind(1) will include my man-page-of-the-day for
that given date.
