Ghost allows you to set two different types of permalink structures - dated, and non-dated. Dated permalinks include the year, month and day within the post URL. For example, yourblog.ghost.io/2016/09/19/welcome-to-ghost/ is a dated permalink, whereas yourblog.ghost.io/welcome-to-ghost/ is not.
To change your permalink structure, follow the steps below.
Log into your blog admin yourblog.ghost.io/ghost/signin.
Click General under the settings menu.
Check the box under Dated Permalinks to include the dates in your post URLs.
