Which is as it should be. Anacron is not for hourly
because it doe snot assume the system is running
continuously. Man page says:

ANACRON(8) Anacron Users’ Manual ANACRON(8)



NAME
anacron - runs commands periodically

SYNOPSIS
anacron [-s] [-f] [-n] [-d] [-q] [-t anacrontab] [-S spooldir] [job]
anacron [-S spooldir] -u [-t anacrontab] [job]
anacron [-V|-h]
anacron -T [-t anacrontab]

DESCRIPTION
Anacron is used to execute commands periodically, with a frequency
specified in days. Unlike cron(8), it does not assume that the machine
is running continuously. Hence, it can be used on machines that aren’t
running 24 hours a day, to control regular jobs as daily, weekly, and
monthly jobs.
