When specifically was the black death?

The Black Death arrived in Europe by sea in October 1347 and ended in 1353.

The Black Death begin in October 1347 in Europe. Opps. I didn't read the question correctly.

The Black Death was a horrific plague. It made people feel ill and gave people nasty black boils. The boils oozed out blood, hence the name, "Black Death". The total death were about 20 million.
