By default the URL for the post is of the form: <domain name>/<year/<month>/<day>/<post title>
This display may not be the most attractive if you want your post still of interest in 5 or 10 years. The date in that case would suggest that the contain may not be relevant anymore.
To change this, you need to go in Settings and select Permalinks.
By default, Day and name is selected.
Change the selection to Post name and click on Save Changes.
A temporary box appears at the top to confirm that the change was saved.
Now let’s go back to the Posts section to see the changes.
Now in the URL, we can see that the date is removed from the link.
