man ancrontab :

------------------------ begin quote manpage anacrontab ---
       The file /etc/anacrontab describes the jobs controlled by
anacron(8).  Its lines can be of
       three kinds:  job-description lines, environment assignments, or
empty lines.

       Job-description lines are of one of these two forms:

          period  delay  job-identifier  command

          @period_name delay job-identify command

       The period is specified in days, the delay in minutes.

-------------------------- end quote manpage anacrontab ---

so i think that cron.daily will be run every day 5 minutes after you
boot up your machine, correct me if i'm wrong

for daily tasks at a certain time i personally prefer to use cron
instead of anacron

see :  man 5 crontab
