Plus:
  man 5 crontab
which has in its section "EXAMPLE CRON FILE"

       # run five minutes after midnight, every day
       5 0 * * *       $HOME/bin/daily.job >> $HOME/tmp/out 2>&1

and explains further up

      The  format of a cron command is very much the V7 standard, with a num‐
      ber of upward-compatible extensions.  Each line has five time and  date
      fields,  followed by a command, followed by a newline character ('\n').
      ...
             field          allowed values
              -----          --------------
              minute         0-59
              hour           0-23
              day of month   1-31
              month          1-12 (or names, see below)
              day of week    0-7 (0 or 7 is Sun, or use names)

So the command shown by Greg Wooledge runs at 6:25 am the comand

  test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )

which runs the programs in /etc/cron.daily (by run-parts(8)) if not
/usr/sbin/anacron exists and is executable.


Have a nice day :)

Thomas
