It might be a flaw, but it's also very handy when you want to represent the months or day of the week as a string you can just create an array like ['jan,'feb' ...etc][new Date().getMonth()] in stead of ['','jan',feb ...etc][new Date().getMonth()] or ['jan','feb' ...etc][new Date().getMonth()-1]

days of the month are normaly not named so you won't be making arrays with names for those. In this case 1-31 is easier to handle, so you want have to subtract 1 every time...
