The Holocene Calendar, also known as the Human Era Calendar, takes into account time since humans began building and went into the neolithic revolution.
To use the Human Era calendar is take into account the time since the current technological explosion appeared, and the first structure built -- the rule of humans officially began. (for good or ill)
The Human Era Calendar solves the B.C. calculations issues since not only negative numbers are complicated to explain in geological and historical terms -- and make calculations with them -- but also because there is no year zero in the Gregorian Calendar we use. And as we know from coding, the zero should be taken into account.
