You're almost there. I don't think you need to go back to JC's birth though.
As someone mentioned earlier the 1900s was the 20th century & the year 2000 was the last year of the 20th century (hence its name).
Therefore 2001 was the first year of the 21st century & 2010 was the last year of the 1st decade of this century & 2020 is the last year of the 2nd decade of this century. 2021 is the 1st year of the 3rd decade. Problem solved.
What has muddied the waters is using the tag, the 20s or the 30s. These are really not mathematical decades, they are just a group of 10 years which share a similar naming prefix.
