I would like to get the date(era) of this MWE

  style = archaeologie,
    author  = {Cicero},
    title      = {De re publica},
    date     = {-0054/-0051},


enter image description here

as described in table 5 of the biblatex documentation:

How can I achieve tihs?

    Option dateera=christian? – gusbrs Jun 9 '18 at 22:11
  • Are you sure you want Christian dates? – cfr Jun 9 '18 at 22:59

    The style you are using prints the era string in some cases, but, in your example, using dateera-christian will produce '55-51' since both years are part of the same era. If the second was a common era year, you'd get '55 BC -51'. I assume you are using this style because you are publishing or hoping to publish in a journal which uses it. Is the style correct for those journals? – cfr Jun 9 '18 at 23:26
  • @cfr If I'm not mistaken, LukasCB is the developer/maintainer of the style. – gusbrs Jun 9 '18 at 23:36

    LukasCB, as far as I was able to trace, the style sets the option alldates=comp. Using both dateera=christian and alldates=long would give you dateera information there. – gusbrs Jun 10 '18 at 0:33

The problem here is that english-archaeologie.lbx has \dateeraprint{#2} instead of \dateeraprint{#2year}. This is similar to issue #679 at the biblatex bug tracker. The code in english-archaeologie.lbx was based on an older version of the biblatex core macros from before the fix.

I have submitted a pull request (https://github.com/LukasCBossert/biblatex-archaeologie/pull/146) with the necessary changes.

I should probably add that all of this is under the assumption that you use


or dateera=secular if you prefer the non-Christian denominations, as suggested by @gusbrs in the very first comment.

  • Ah! It was in the .lbx! (+1) – gusbrs Jun 10 '18 at 10:45
