How to format CE/BCE?

Yes, there is the abbrevs package. It provides me with AM, PM, BC and AD. But what would be a sensible way to format the "Common Era" / "Before Common Era" prefixes / suffixes?

• I'm not a nativ english speaker. I can't see your problem. Can you please explain it a little bit more, for example with showing a MWE and/or a screenshot which shows what you have and what you want? What has the tag fontsize to do with your question? – Mensch Jun 9 '13 at 14:03
• Why not define analogous commands to \AM, \PM ...? \AM is defined by the abbrevs package as follows: \newcommand{\AM}{\DateMark{a.m}} – cgnieder Jun 9 '13 at 14:06
• @cgnieder: Thanks, that helps. In general, how do you look up these definitions? Where can you find them? – chaosflaws Jun 9 '13 at 23:55
• @chaosflaws They're mentioned in the implementation part of the abbrevs documentation. If they weren't I'd either have opened the abbrevs.sty file or would have used \meaning\AM. – cgnieder Jun 10 '13 at 7:34

You can define them analogous to the definitions of \BC and \AD which are defined by the abbrevs package as

\newcommand\AD{\DateMark{a.d}}
\newcommand\BC{\DateMark{b.c}}


The \DateMark macro takes care of eventual following punctuation and formats its contents with \DateMarkSize and \scshape. \DateMarkSize is \small per default which I'd change: the punctation marks in e.g. A.D. else will be of different size and it seems strange to me to use a fixed size for the marks, anyway: think of using them in a footnote or something...

\documentclass{article}
\usepackage{abbrevs}
\newcommand*\CE{\DateMark{c.e}}
\newcommand*\BCE{\DateMark{b.c.e}}
\begin{document}

\BCE \CE

\CE, \CE.

\end{document}


• Hmmm .... I don't get this output from this code. Do you know if anything changed? – cfr Sep 15 '16 at 12:10
• It seems this code worked three years ago. No idea if there have been changes. I never really used abbrevs – cgnieder Sep 15 '16 at 12:12
• Me neither. Somebody asked a question. I think it is a bug, though. – cfr Sep 15 '16 at 12:27
• Which reminds me of tex.stackexchange.com/a/59884 abbrevs has bugs – cgnieder Sep 15 '16 at 12:32
• Seems the new question is a duplicate. And according to the comments I even made a bug report. – cgnieder Sep 15 '16 at 12:40
