Now that I have recorded in one place all of what the Wikipedia community considers the significant events in history, the question comes up of how to update the list. I suppose I could scrape all those Wikipedia pages again, but history actually only advances one day at a time.
On some days, new historical events are added, but on most days they are not. So I suppose I could have a manual or automatic daily process of checking to see whether any new events were added for today — the current day of the current year.
If so, I just update that one day in my database and regenerate the list. If not, then there is nothing to do.
But one thing I don’t know is whether Wikipedia ever deletes an historical event. Does the list just keep getting ever longer, or is it ever pruned?
I’m not even sure I would know how to find out.
