I'm looking for a plugin, which may not exist, that either reposts or refreshes a post every year on the same day. In other words, say I have a post for a famous author on his birthday and I'd like it to show up every year, whether I post anything else or not on that day, automagically.
I searched, but didn't find anything that quite did this. On This Day came close, but that only displays things that have been posted already on that day and only if you manually create a post for the day in question.
Thanks in advance!
