Happy Creation Day!

Saw this post over at Phyrangula.  I  too forgot today (October 23) was the date Archbishop James Ussher (1581-1656), Primate of All Ireland set as the day of creation in the Bible in 4,004 BCE.  Happy 6013th birthday Earth (actually 4,600,000,000 years old, but what's a six orders of magnitude between friends?).
