1300 - 500 = 800. About right.

1300 + ~700 = ~2000. Uh oh.

The astronomers in some of these linked articles say that the next best chance for a (somewhat predictable) comet swarm is about the year 3,000.

Here's what they said:

"The calculations for the Taurids suggest that we pass through the core of the meteor stream approximately every 2,500 years - today, we are passing through the outer edges. The last two occasions when we passed through the core were in 2200 - 2000 BC and in AD 400 - 600. The epoch around AD 3000 looks like being a fun time too - the Y2K doomsayers can always say they just got the millennium wrong."
