I want to fit the title in the footnote and use the date space in title removing date.

Looking at the footer definition of this template, one finds:

\defbeamertemplate*{footline}{infolines theme}
{%
\leavevmode%
\hbox{%
\end{beamercolorbox}%
\end{beamercolorbox}%
\end{beamercolorbox}}%
\vskip0pt%
}


Since you want some bigger changes, I'd recommend to rewrite it:

\makeatletter
\setbeamertemplate{footline}{%
\leavevmode%
\hbox{%
\end{beamercolorbox}%
\end{beamercolorbox}%
}%
\hspace*{2ex}
\end{beamercolorbox}
\vskip0pt%
}
\makeatother


You can change the widths of those boxes that are set currently with wd=.333333\paperwidth.

In a MWE, including a slightly changed version for including the institution on page two:

\documentclass[usenames,dvipsnames]{beamer}

\makeatletter
\setbeamertemplate{footline}{%
\leavevmode%
\hbox{%
\end{beamercolorbox}%
\end{beamercolorbox}%
}%
\hspace*{2ex}
\end{beamercolorbox}
\vskip0pt%
}
\makeatother
