'Let's go to Holland.' 'Oh, the Netherlands?' 'Well yeah because Holland is in the Netherlands.' 'Isn't Holland also the Netherlands? The Dutch live there right? Why are they called Dutch if they're from the Netherlands?'
People often use the names Holland and Netherlands interchangeably like United States to America. However, using either words to describe one country isn't technically correct. To give you a quick answer, just remember: Holland is a province and the Netherlands is the country.
