I often wonder what significant anniversaries are due at some point in the future as some of them might be of interest as triggers for blog posts or visits somewhere. However, it is often difficult to find out quickly what events have significant anniversaries - hence this section on the website.
By "significant anniversaries", I mean dates that are not, for example, the 73rd anniversary of something, but the 50th, 100th, 200th etc.
It should help to flag up interesting events.
