Inserire giorno della settimana da calendario

[morangel]

Buongiorno, ho un form in asp dove inserisco la data tramite calendario con questo script e funziona bene, ma mi inserisce solo la data esempio 05/12/2014, vorrei fare in modo che mi inserisse anche il giorno della settimana ovvero Venerd' 05/12/2014 come posso fare? grazie in anticipo
per inserire utilizzo

<input name="Data" type="text" id="Data" value="<%=response.Write(Date())%>" size="10" />
