I have been looking for rules applying to reading dates like 150 AD but I haven't found reliable information.The only rules I can find are about typical (current) dates. I would be very grateful for any help.
Have a look at this:
If I were reading what somebody else had written, I might read it as any one of these:
a/one hundred and fifty A D
A D a/one hundred and fifty
one fifty A D
A D one fifty
As AD stands for anno domini, which is Latin for in the year of our Lord, some people say these two letters before the number of the year.
If the words were my own, I would use CE instead of AD.
I'd read it aloud as "a hundred and fifty A D" or "one hundred and fifty A D".
I still can't get used to "CE" - for the life of me, I can never remember whether it's meant to be a replacement for BC or AD.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
Whoever devised BCE and CE didn't think it through very well.
I always think of them as 'Before the Christian Era' and 'Christian Era' which defeats the object of the neologism.
They are certainly not ideal. Even if you accept the C as standing for common, this system of numbering years is by no means universally accepted (see here). If there were such a thing as the Common Era, it certainly did not begin 2,016 years ago.Until less than 400 years ago, most of the world's inhabitants knew little or nothing of the existence of peoples living more than 500 miles away, and only Christians might think of a common era. I imagine that the idea of a common era based on the supposed birth year of the holy figure of the Christian church is not very appealing to many non-Christians.
I use CE because there is no better term that I can find.
Given that the calendar has to start somewhere, what historical event should be used? I'm at a loss.
I have no objection to this year being numbered 2016. As you say, we have to start somewhere, and the birth of a man revered for centuries in the countries which use this system is as good a place as anywhere, particularly as it is so well established. However, in the current world, one in which Christians are a minority group, albeit a very large and influential one, I am not happy about AD and, now that I have started to think about it, CE also has problems. Perhaps the easiest thing of all would be to use plus and minus signs. Thus 55 BC(E) becomes -55, and 1453 AD/CE becomes +1453. As with AD/CE the plus sign could be dropped unless considered necessary. We'd soon become used to, for example, The Romans left Britain in the +5th century.
