Eh no. Let me also be clear I say this and cannot remember the date of Pearl Harbor, Cherynobl, or a number of other major events.

9/11 is a bit of a weird case in that the name of the event is also the event itself... that usually does not happen.

Please label your dates folks (except 9/11 I guess...)

"Tiananmen Square" is the English name for the event. The name in Chinese is the "June 4th Incident", much like 9/11 in English.

Since the blog is in English, a "translation" might have been helpful; but since he goes so much into Mandarin, perhaps he assumes his readers are already familiar with the Chinese name.

That's just US-centric. For example, you probably don't know off the bat what happened on 22.06.41 either, but if someone buys an ad in a Russian newspaper encoding these figures, it would be perfectly reasonable to say "everyone knows".

"9/11" is not generally referred to as such outside the US, and would more usually be described as the September 11th Attacks. Also a date, but less numerical.

I'd prefer September the 11th. I can never tell from dates if the day isn't over 12 whether it's in american or everywhere else date format.

I remember the Fourth of July! And New Year's Day, and Cinco de Mayo. Not so weird?

I don't usually remember Cinco de Mayo :>

But you remember when it is?

And who's buried in Grant's Tomb?

Grant who?

December 7th 1941 a date which will live in infamy.

What happened on the 9th November?

As the song goes: "Remember remember the fith of November", but I don't remember the 9th.

...supposedly universal cultural references are hard :-)

In Germany, quite a few notable, good and bad, things happened on the 9th of November.

Only when you're clearly not the target audience.

That was the morning we found out Trump was elected.
