Will a crontab job wake OS X up from sleep?

Question

Since OS X has its own task scheduler, launchd, it appears that crontab is a relic.

Hence I'm wondering: Will a cron job (crontab) wake OS X up from sleep?

In case it matters, I'm on Yosemite 10.10.5.

Why I'm not switching to launchd? Laziness:

> man launchctl | wc
     463    2975   27730
> man crontab | wc
      72     433    3577

The man page is a lot larger, and crontab does everything I need.

I would delve into the Terminal command pmset and find out how to schedule startup/wake from sleep. A little testing should show you, as an example, if waking the Mac from sleep at 2:55AM with pmset, a cron job set for 3:00AM will run as expected. — IconDaemon, Feb 24 '16 at 21:44

cron doesn't execute while the computer is asleep. So cron can't wake your system.
