WP, the date vs get the date in loop
Why the the_date function on WordPress won’t display some dates?
In the loop to display posts on your blog the function the_date probably won’t display all the dates, but the get_the_date will do.
Why the_date is not working but get_the_date is working?
The_date(), will not display the same date if another post has the same date, but get_the_date will display, so we recommend to the get_the_date()
