as far as i can see it is not explained in http://jqueryui.com/demos/datepicker/#option-minDate

$('.selector').datepicker({ minDate: new Date(2007, 1 - 1, 1) });

I understand the 2007.

I did some troubleshooting and i think the firts 1 stands for the month.. so what does the second 1 stand for (the one after the - and before the ,)?

I gues that the last 1 stands for the day, please confirm.  THNX !!
