cutting down my JS file!

Hi,

Im looking to cut down this javascript file a lot but im not quite sure how to go about it? there are a lot of repeating features in the code so im assuming its possible..... any ideas on how i could do this? as much help as possible would be appreciated as im new to the javascript game :)

var monthAbbreviations = new Array("January ", "February ", "March ", "April ", "May ", "June ", "July ", "August ", "September ", "October ", "November ", "December ");
var daysOfTheWeek = new Array("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday");
