You can publish changes at a future date and time that you specify. You can also set up a schedule to publish changes at regular intervals, for example, nightly.
To create a publishing schedule:
Click the Publishing tab.
At the top of the updates list, click Publish and then select Schedule Publish.
Specify a date and time to publish. Both date and time are required; there are no default values for either.
The date and time you specify here use the time zone you configured on the General settings tab.
Click Schedule.
(Optional) To set up intervals to publish changes, repeat steps 3 and 4 for each new future date and time you want to specify.
