The last time the sunspots disappeared altogether was in the 17th and 18th century, and coincided with a lengthy cool period on the planet known as the Little Ice Age....and lasted 400 years.

so the little Ice age has lasted from 1600 to somewhere in the 1900s?

NASA defines the term as a cold period between AD 1550 and 1850
