A bit, yes. Today's my birthday, and it's always been labeled as "ANZAC Day" on every calendar I've ever had, but I could never find anything about it until recent years. It was a private joke of mine to go around wishing people a "Happy ANZAC Day" because no one ever knew what I was talking about. Sometimes I change in up with "Happy Italian Liberation Day" (which is also today).
Also, I like wishing people bizarre/little-known holidays such as World Turtles Day (May 23) and National Sleepyhead Day (July 27) so it's a win-win situation for me.
