I strongly suspect 1998 was a typo by OP and he was actually pointing out the discrepancy between 2 Nov and 4 Nov WRT “this day”.

However the article has been updated so only the HN title has this flaw.

Sounds like the type of mistake I always make: Notice someone being off by two days, and in haste, post a correction that is off by ten years.

With that username you don't even need to be all that close to get the job done.

I think his question was whether it was Nov 2 or Nov 4...
