Answer 1

You need to specify what amount of time you are subtracting. At the moment its 1, but 1 what? Therefore, try getting the days using getDate() and then subtract from that and then set the date with setDate().

E.g.

var temp = new Date("October 13, 2014 22:34:17");
temp.setDate(temp.getDate()-1);
