Facebook has now given the users of Facebook pages the ability to schedule posts
TO schedule a post, first click on status and compose your post
At the bottom left there is a small clock, select this
Here you will be asked the year, month, day, hour and minute (the minutes go up in 10 minute increments)
Once you have done this select Schedule, your status will be posted at the time you have selected
To view scheduled posts, change time of posts or cancel posts
Go to the Admin page
Select Manage > User Activity Log
This will display any posts waiting to be sent
Go to the right of the post and select the drop down menu to change post time or cancel
