I know about the AD/CE distinction, and it wasn't what I meant.
The calendar that is the same every year, always 12 months and with the seasons always falling into the same months, is not inherent to the nature of the universe. It was adapted and enforced by Christian Rome in order to preserve the symbolism of new life in early spring and the annual commemoration of Easter in perpetual sync. It was a revolution away from the established calendars of Judea, Greece, early Rome, and basically every prominent cultural influence around them, whose calendar dates were synced to phases of the moon rather than seasons of the year.
You not only use a calendar designed to commemorate the deity of Jesus, but you did not even know an alternative existed. Anders Behring Breivik did not kill for believers in Christ, but for people like you who live a cultural tradition created by Catholic Rome and spread across the world by its civil heirs. Breikvik killed for Rome, not for God; that is, secular western society, not religion. That is why Christian believers object to non-believers blaming the Norway shooting on Christian theology. It is not only wrong, but ironic and backward.
AFAIK the Britons who built Stonehenge were very big on the solar year, as were the Egyptians. Months, days, etc don't have anything to do with that, except I think most people would also have the concept of day. So then they figured out how many days it took for the sun to complete one cycle. Tho I don't know for sure, I bet the calendars of Judea, Greece etc also followed the solar year. So when you speak of an anniversary, that is what you are referring to.
I haven't really heard the Norway shooting blamed on Christian theology, as it would have been had this been Muslims - probably with no more justification.
