In 999BC, something stopped happening that had been happening for the past 999,001 years. This thing did not happen again until 1000 AD, but now it will not stop happening until 1000000AD. (of course, 1,000 years after that, it will occur again for another 999,001 years....)

So what is this thing? Tell me if this is too obvious, please.... I made it up.

Does it have something to do with the year having a 1 followed by 3 or more zeros?

The letter A appears if you write out the number of the year longhand.

Nine hundred ninety nine has no A, but one thousand does.

The solution doesn't explain this.

If you are not counting AD in every year! there are quite a few in between that have and don't have A in them.
Good try but no cigar - back to the drawingboard I think Kay.

I was off with precession I think it's every 25k years, I'll check it later.

I rather liked that one. I had never stopped to think that the written numbers zero through nineteen as well as twenty, thirty, ... , ninety, and one hundred contained no instances of the letter 'a'. A strange and interesting fact.

By the way, I think the "event" was the appearance of the letter 'a' in the longhand written version of the year number, so yes, I do believe the solution explains that the event stopped happening, because 'a' stopped appearing.
