At system startup via the init script (or systemd service or upstart
job) or using systemd timers (tough this isn't shipped with the anacron
package).

systemd itself ships systemd-tmpfiles-clean.timer which runs a daily
job, similar to how anacron itself works:

+-----
| [Unit]
| Description=Daily Cleanup of Temporary Directories
| Documentation=man:tmpfiles.d(5) man:systemd-tmpfiles(8)
|
| [Timer]
| OnBootSec=15min
| OnUnitActiveSec=1d
+----[file:///lib/systemd/system/systemd-tmpfiles-clean.timer]
