How to print "Spring" if in month is in Jan-June? Otherwise "Fall"?

Question

I teach classes and in my notes I have "Fall 2015" during fall semester and "Spring 2016" during Spring semester. I can use

\the\year

for the year. But is there something like

\the\season

for Fall and Spring? And if so, how can I customize which months define the semester?

year is a count register, but season is a range of counter values actually — , Feb 12 '16 at 19:22
Of course, all this breaks down if you want to get ahead of things and produce some notes for spring term in December, for instance. Seems that something like \newcommand\term{Spring 2015} is simple and easily changed for next term. Sometimes over-automation creates more work than it alleviates. — dedded, Feb 12 '16 at 20:46

Without any extra package and providing support for northern or southern hemisphere:

\documentclass{article}

\newif\ifnorthernhemisphere
\northernhemispheretrue

\newcommand{\season}{%
  \ifnorthernhemisphere
  \ifcase\month
  \or Winter
  \or Winter
  \or Spring
  \or Spring
  \or Spring
  \or Summer
  \or Summer
  \or Summer
  \or Fall
  \or Fall
  \or Fall
  \or Winter
  \fi
  \else
  \ifcase\month
  \or Summer
  \or Summer
  \or Fall
  \or Fall
  \or Fall
  \or Winter
  \or Winter
  \or Winter
  \or Spring
  \or Spring
  \or Spring
  \or Summer
  \fi
  \fi
}



\begin{document}
Northern hemisphere

\the\month\ \season

\month=5
\the\month\ \season

\month=9
\the\month\ \season

Southern hemisphere

\month=2
\northernhemispherefalse
\the\month\ \season


\month=5
\the\month\ \season

\month=9
\the\month\ \season

\end{document}

Update Here's a variant with optional argument:

\documentclass{article}

\newif\ifnorthernhemisphere
\northernhemispheretrue

\newcommand{\season}[1][\month]{%
  \ifnorthernhemisphere
  \ifcase#1
  \or Winter
  \or Winter
  \or Spring
  \or Spring
  \or Spring
  \or Summer
  \or Summer
  \or Summer
  \or Fall
  \or Fall
  \or Fall
  \or Winter
  \fi
  \else
  \ifcase#1
  \or Summer
  \or Summer
  \or Fall
  \or Fall
  \or Fall
  \or Winter
  \or Winter
  \or Winter
  \or Spring
  \or Spring
  \or Spring
  \or Summer
  \fi
  \fi
}



\begin{document}

\season


\season[5]


\season[9]

One could add a babel hook to setup seasons names according to the current language or even use datetime to format any date, like, for example, \season\today. Hope it helps! :)

What about:

\documentclass{article}
\usepackage{ifthen}

\begin{document}

The term now is: \ifthenelse{\month<6}{Spring}{Fall} 

\end{document}

With the ifthen package you can build quite complex conditional text.

Obviously you have to adapt it to your case, but you can nest \ifthenelse and even use \month or \day in it to fine-tune the result.

The term now is: \ifthenelse{\month<9}{%
    \ifthenelse{\month<6}{Spring}{Summer}}%
    {Fall}

(this last suppose Spring term for Jan to May, Fall from Sep to Dec, and the rest Summer. YMMV)

@Sigur: That's hard to track from LaTeX unless there are geolocation tools in LaTeX ;-) – Feb 12 '16 at 19:27
@ChristianHupfer And what about TeX? You used TeX primitives in your answer, this has no connection to LaTeX. – wipet Feb 12 '16 at 19:36
@wipet: Fair point. I know, you find LaTeX horrible, especially mixing TeX and LaTeX, but in this case I found TeX much simpler. If I would kick out the LaTeX specific commands it would work with TeX too, I suppose – Feb 12 '16 at 19:43

A biblatex solution, for when there are multiple or archival items.

Treating the season as part of the publication (meta)data.

Localisation can also come into play. (Note that not all babel/polyglossia languages define season-related strings (yet).)

Automating

A more generalised solution, using a custom code number.

Biber can do the four seasons using the date field when the month is set to certain values:

  my %
    seasons = ( 21 => 'spring',
                  22 => 'summer',
                  23 => 'autumn',
                  24 => 'winter' );
...\texlive\2020
\texmf-dist
\source
\bibtex
\biber
\biblatex-biber.tar
\biblatex-biber
\biblatex-biber-2.15
\lib
\Biber
\Date

format.pm

Extending that idea, but using instead a custom field (term) processed via macros at Biblatex/Latex-level, University Terms and Court Terms can be done:

Illustrating the use of the xsv field type and associated \forcsvfield command, allowing customised sequencing of fields on a per-bibentry basis (and the expl3 split function); and formatting hooks within the citation command, allowing the changing of the citation format mid-document; and bibstrings for localisation. Plus an example of using a field as an input argument to arbitrary code using \usefield (here, an image name).

An exercise in what could be done.

Use-case: sets or compendia, or other bulk volumes?

Terms can always be keyed in manually if there are only a few, or the issue field of @article could be used.
