Is 2021 the Start of a New Decade?
okay first of all y'all don't even know how to count you go from 0 to 1 and that's one same with the first year as well it starts with zero then 24 hours pass it becomes a day then 6 months pass it becomes half a year another becomes one but the entire year counts as one and a decade doesn't mean add it means a whole group of ten it's like saying a year is adding one year so essentially a year doesn't pass on year 1 it passes in year 2 with that logic we call it 1 year because it's a whole group of 1 year duh a group of ten is a decade a group of 100 is a century etc basically learn to count
Referring to centuries by cardinal numbers, we have "the 1900s" (1900-1999), "the 2000s" (2000-2099), etc.
Referring to centuries by ordinal numbers, we have "the 20th century" (1901-2000), "the 21st century" (2001-2100), etc.
Referring to decades by cardinal numbers, we have "the 2010s" (2010-2019), "the 2020s" (2020-2029), etc.
Referring to decades by ordinal numbers, we would theoretically have "the 202nd decade (2011-2020), "the 203rd decade (2021-2030), etc.
Notice that one of these is not like the others. We "would theoretically" refer to decades that way using ordinal numbers -- except that *nobody actually does that*.
Decades are 0 to 9. Q.E.D.
a decade started at the '0', especially after experiencing the dreaded turn of the century just 21 years ago...remember Y2K? But I do understand our number system as well. For example, our ages. If someone is born on April 2, 1960, their first birthday is held on April 2, 1961. On that date, they're actually starting to live in their SECOND year, not their first year, since they just lived through their first year. I actually try not to think about it too much or it'll blow my mind! ;c)
