Yes! You can Plan as far into the future as you wish, AND you can also keep your members from seeing planned workouts until you want them to see them.

To set the time on when you would like your WODs to be "released" you need to go to your admin console. Head to your profile drop down on the website, then select "Launch Admin Console."

On the right side of the screen select "Settings" followed by "Prefs". 

Make sure your proper time zone is selected. You'll be able to set the exact display time. Options range from 1pm the afternoon before to 11pm the evening of. 

Save your preferences to begin hiding your workouts. These preferences only apply to tracks that have been set as "hidden". You won't be able to set different release time for different tracks. To learn how to hide tracks, view Can I hide planned workouts for different tracks?
