RE: K-T impact in early June?

In the spirit of determining the age of events long past...I'm reminded of 
James Ussher (1581–1656)
Anglican Archbishop of Armagh and Primate of All Ireland [Earth was created 
Sunday 23 October 4004 BC]

Of course James Ussher was a tad off on his calculations but so many 
advancements have been made in the science of dating since

The K/Pg impact event was in early June...or correctly according to John 
Schneiderman as Thursday 7 June 66,231,962 BCE
Unfortunately the popular tabloids of the day states 65,502,015 BCE without 
month or day mentioned...so who are you going to believe...oh and by-the-way: 
the last non-avian dinosaur [a Triceratops horridus] died 3 days later, thus 
there were Paleogene dinosaurs.
