If the machine is up at midnight and it's been N days, yes.

Well, what time would you like them to try to run?
If you want e.g. 4 AM, try setting the delay to 4 * 60 = 240 minutes.
Another thing you can do to reduce the impact of all the cron
scripts trying to run at once is use the -s (serialize) option.
Then anacron "will not start a new job before the previous one
finished." (it's not clear to me if "start" includes the delay
or not.)
