WordPress supports scheduling of posts. You can schedule them to publish in the future. They are published on the foreseen publishing date.
For example while you are on holiday.
From time to time, this publishing fails. In the post view of WordPress admin (dashboard/post list/scheduled posts/last page) these articles are then marked ‘Missed Schedule’.
It is not completely clear to me, why this happens. But on one of my WordPress powered sites scheduling worked for a long, long time as expected, just to fail from one day to the other. (It was just luck, that I noticed this at that time.) As I really like and need scheduling, I analyzed the problem and finally found a solution.
