\today month as text

From the datetime manual, you have two solutions:

• either use the predefined shortdate format, which will print "07th may, 2013";
• or define a new date format to get rid of the ordinal as well.

\documentclass{article}
\usepackage[a5paper]{geometry}
\usepackage[nodayofweek]{datetime}

\newdateformat{mydate}{\twodigit{\THEDAY}{ }\shortmonthname[\THEMONTH], \THEYEAR}

\begin{document}

\shortdate
\today

\mydate
\today
\end{document}

Here is an humble attempt without having to use any package:

\documentclass{article}
\renewcommand{\today}{\ifnum\number\day<10 0\fi \number\day \space%
\ifcase \month \or January\or February\or March\or April\or May%
\or June\or July\or August\or September\or October\or November\or December\fi,%
\number \year} 
\begin{document}
\today
\end{document}
