Enquanto pesquisava minha resposta a essa pergunta Sabemos quando Daenerys Targaryen nasceu? Me deparei com uma ligeira estranheza em como a wikia de Game of Thrones mostra as datas. Datas para o show parece ser dado em BAL e AL significado (Antes) Aegon's Landing.
The dating system is based on Aegon the Conqueror's first landing on Westeros which started the Targaryen Conquest. Thus all dates are "AL" for Aegon's Landing or "BAL" for "Before Aegon's Landing".

No entanto, as datas nos livros são dadas em BC e AC, significando "Antes da Conquista" e "Depois da Conquista", respectivamente.
The maesters of the Citadel who keep the histories of Westeros have used Aegon's Conquest as their touchstone for the past three hundred years. Births, deaths, battles, and other events are dated either AC (After the Conquest) or BC (Before the Conquest).

Eu dei uma olhada e encontrei uma citação explícita do GRRM sobre o raciocínio da mudança de datas no programa em comparação com os livros, basicamente para manter o sexo e a nudez.
There was a fair amount of explicit sex in the series and some fans of the books were taken aback.
One of the reasons I wanted to do this with HBO is that I wanted to keep the sex. We had some real problems because Dany is only 13 in the books, and that’s based on medieval history. They didn’t have this concept of adolescence or the teenage years. You were a child or you were an adult. And the onset of sexual maturity meant you were an adult. So I reflected that in the books. But then when you go to film it you run into people going crazy about child pornography and there’s actual laws about how you can’t depict a 13 year old having sex even if you have an 18 year old acting the part — it’s illegal in the United Kingdom. So we ended up with a 22 year old portraying an 18 year old, instead of an 18 year old portraying a 13 year old. If we decided to lose the sex we could have kept the original ages. And once you change the age of one character you have to change the ages of all the characters, and change the date of the war [that dethroned the Mad King]. The fact we made all these changes indicates how important we thought sex was.

Isso faz sentido, já que com mudanças de idade, outras datas precisam ser alteradas também, então a história ainda se alinha corretamente. Como tal, faz sentido que eles mudaram o sistema do ano no programa.
No entanto, eu ainda não encontrei nenhuma menção oficial, ou canônica, do sistema do ano do programa como AL. Tudo o que eu encontrei até agora é wikia apenas usando as datas, mas nenhuma menção de onde eles conseguiram isso.
Existe alguma menção oficial do programa mudando as datas no show para AL do AC?
