It's cracking me up that the question "Does 2020 actually start a new decade?" has been of such hot debate online.
Teachers, this would be a great topic of discussion as your students come back to school. Let them figure out if it is with supporting details.

Let's clarify this...
2010 = 1 year
2011 = 2 years
2012 = 3 years
2013 = 4 years
2014 = 5 years
2015 = 6 years
2016 = 7 years
2017 = 8 years
2018 = 9 years
2019 = 10 years
10 years = Decade
2020 = NEW DECADE
END OF!
