Use Wix Automations to publish your site at a specific date and time automatically. If you’re launching a special design or updating for an event, you don’t have to publish the changes manually. By pairing the 'Publish site' action with a 'Scheduled Time' trigger, you can automatically publish your new site design on the selected date and leave the tedious tasks to automations.
To schedule your site to publish:
Go to Automations in your site's dashboard.
Click + Create Automation at the top right.
Click + Start from Scratch to begin from a blank automation template.
Click the title to give your automation a name.
Click Scheduled time as your trigger.
Select a Start date.
Select a Start time.
(Optional) Enable the Repeat toggle:
Set how often the trigger repeats (e.g. day, week, month).
Click the drop-down menu to select an End:
Never: Trigger doesn't have a set end date.
On specific day: Select a specific date for the trigger to end.
(Optional) Enhance your automation further by adding a Condition, Delay, Local variable or Global storage item.
Click the Add Step icon
and add an Action.
Click Publish site.
Click Activate or Save at the top right.
