And is it just a coincidence the 60 year cycle aligns with "0" years in the CE calendar?

The cycle of 60 is already present in Shang oracle bone inscriptions, so to the extent this question is meaningful the answer must be "yes".

However, I don't see that the 60-year cycle does align with the CE calendar; what's special, or "aligned", about year 37 in one calendar being year 40 in another calendar?

Any year in the cycle of 60 that lines up with an Anno Domini year that is a multiple of 10 will always continue to do so, since the cycle of 60 repeats every 60 years, and 60 is a multiple of 10. There will obviously be 6 such years†, no matter where cycle year 1 falls Anno Domini.

† Assuming the Chinese year and the Christian year start on the same day, which is false for most of history.

P.S. my autocorrect thinks "gengzi" should be "gandhi" ]]>
