I Use AD and BC (and if that bothers you, maybe my content isn't for you)

Here is a man who has the CE / BCE system, my parenthesis is borrowed with adaptation from his last line:

The Real Reason We Stopped Saying BC

1:07 "each had its own system and start date"

No. Ab urbe condita was a fairly unique way of counting and wasn't used in current dating.

You dated things to "the year of Cicero and Hybrida" not to "63 BC" or to "690 aUc".

Greeks, Egyptians, diverse realms of Mesopotamia, all lacked this system. OK, I'll need to make a caveat about Greeks: they had a somewhat close thing to an exception, the Olympiads. But even so, you dated in current dating to "the year of Solon" for 594 BC and not to "third year of the 45th Olympiad" ...

2:00 I'll have wiki correct you on China:

An epoch is a point in time chosen as the origin of a particular calendar era, thus serving as a reference point from which subsequent time or dates are measured. The use of epochs in Chinese calendar system allow for a chronological starting point from whence to begin point continuously numbering subsequent dates. Various epochs have been used. Similarly, nomenclature similar to that of the Christian era has occasionally been used: [list of five alternative epochs] No reference date is universally accepted. The most popular is the Gregorian calendar (公曆; 公历; gōnglì; 'common calendar').

Similarily, there are several Anno Mundi calendars concurrently : Jewish, Samarian, Byzantine. If you like, Yasidi too. It would seem none of them was in current use in BC times. To be fair, AD also wasn't in current use in early AD times.

2:29 I think the earliest reference to Kaliyuga is from 499 AD:

Astronomer and mathematician Aryabhata, who was born in 476 AD, finished his book Aryabhatiya in 499 AD, in which he wrote "When the three yugas (satyug, tretayug and dwaparyug) have elapsed and 60 x 60 (3,600) years of kaliyug have already passed, I am now 23 years old." Based on this information, Kali Yuga began in 3102 BC, which is calculated from 3600 - (476 + 23) + 1 (no year zero from 1 BC to 1 AD).

4:36 Before AD was used for common reckoning of everyday events, we are already in c. 1100 AD.

BC came into common use in the Renaissance.

You haven't replaced it.

If Muslims and Jews are OK with using it, I don't see why they shouldn't use AD and BC too, but if they don't, I don't see why the rest of us should follow suit.

6:39 The Beowulf poet and I have a different view on how we respect pre-Christian cultures.

From you.

In the quote from the last, I corrected CE and BCE to AD and BC. For convenience, I don't always do that, though.
