Hi. I hope this is an appropriate place to ask this question. Please do let me know if it's not. I'm looking for a website (or other resource) that lists anniversary dates for major historical events.

I do programming for a public library and we like to peg author talks to relevant anniversaries. While I'm pretty well versed in areas like American politics, I often miss major anniversaries in other areas ... particularly world history and military history.

Thanks in advance for any help you can provide.
