General ⇒ \today in ISO format

[drpartha]

I have strange problems when I try to display \today in ISO format. I tried the datetime package. Here is a MWE:

Code: Select all

\documentclass[a4paper,12pt]{article}
\usepackage[yyyymmdd]{datetime}
\renewcommand{\dateseparator}{--}
\begin{document}
Today is::: \date{\yyyymmdddate\today}
Today is::: {\yyyymmdddate\today}
\end{document}

Almost anything I do leads me to errors. Here is a summary ::

Code: Select all

\usepackage[yyyymmdd]{datetime} %gives error Unknown option yyyymmdd
Today is::: {\yyyymmdddate\today} % gives error Undefined control sequence
Today is::: \date{\yyyymmdddate\today} %gives error Unknown option yyyymmdd

How exactly do I get the ISO format for \today ?

Many thanks,

partha

PS I tried the package isodat, but I have other problems there. Will post separately

Hi, a little hint. Marking up code correctly gives you the possibility to directly compile the code with an online editor. This can be handy to rule out faults in ones own system.
Please add \listfiles to very beginning of your document and run the example. What does the file list say?

When calling the documentation via texdoc isodate, what version info does it give you?

I tried the hints given by Johannes_B Site Moderator. I do not seem to move forward. Please help me, or give me a location where I can get some workable solution. I am desperate.

I figured it out !

Code: Select all

\documentclass[american]{article}
%\usepackage{babel}
\usepackage[iso]{isodate}
\begin{document}
Today is ::: \today\\
Happy ?
\end{document}

It works now.

Thanks for putting up with me.

All is well that ends well.
