alt Hacker NewsThe glitch starts with the existence of “year 0”: there's no such thing in the Christian calendars, it goes straight from 1BC to 1AD. (Zero didn't even exist in the 6th century when the Anno Domini epoch was set).

> Second, in the proleptic Gregorian calendar with astronomical year numbering (which is the calendar that we use on 28times),
Non-Julian calendar.

They acknowledge that in the article, and make it clear that it really refers to 1 BC.

And that's also why we are in the 21st century, not the 20th.

First year is actually zeroth, just shifted by one. Calculations start with zear.

They're just using astronomical year numbering.
The article refers to the astronomical calendar, which is differnent from the gregorian by having a year 0, which makes calculations simpler. After year 1 the years have the same numbers, but before 1 they are off-by-one.
Years before 0 is indicated with negative numbers, e.g -50 corresponds to 51 b.c.
