Click on the Calendar tab to open the calendar interface.

Your screen will display the calendar interface:

Click on the specific date you want to schedule your post, then click the plus (+) icon.
A modal will open with the post creation form. The selected date and current time will be automatically filled in.

Fill out all required fields and submit the form to schedule your post.
On the right side of the calendar, you'll see a list of all posts scheduled for the currently selected date.

To view posts for a different date, simply click on another date in the calendar. The list will update to show all posts scheduled for that date.
