Good point - and even though BCE (Before the Common Era) and CE (Common Era) are sometimes used, it isn't enough and seems like a cave-in compromise with the so-called powers that be.

It should be noted that the so-called Christian calendar is off by several years, as the monk who created it circa 600 AD - I mean CE - miscalculated. So we aren't even following an accurate calendar.

Where should we start a new, more secular calendar? When Copernicus published his book De Revolutionibus? When Isaac Newton was born or when he published The Principia? When Einstein was born or from his Miracle Year? Or how about Carl Sagan's birth year?
