datetime
In my generated letter I use \formatdate{\MDay}{\MMonth}{\MYear}. In header I specific \usepackage[nodayofweek,level]{datetime}.
I have got then date like 10th May, 2012, but I would like only 10th May 2012. The same problem is in the address block, where is actual date generate automatically.
How can I check this?
The isodate package allows for various formatting of language-specific dates. The command \cleanlookdateon removes the ordinal numbering of the day and simply prints it as a numeric:
\documentclass{article}
\usepackage[UKenglish]{babel}% http://ctan.org/pkg/babel
\usepackage[UKenglish]{isodate}% http://ctan.org/pkg/isodate
\begin{document}
Original date format: \today \par
\cleanlookdateon% Remove ordinal day reference
Modified date format: \today
\end{document}
edit: As noted by @Sean Allred, datetime has been superseded by datetime2.
Using the package datetime with the option yyyymmdd as
\usepackage[yyyymmdd]{datetime}
you just change the value of \dateseparator to replace the default / by - (or -- if you want).
\renewcommand{\dateseparator}{--}
Also as noted by @Vincent, you can define your own date format.

The comma as a separator is actually hardcoded into the various definitions of
\formatdate, but you may use theetoolboxpackage to remove it.
