I have seen some excellent checklists for the countdown to a wedding in my time as a celebrant, however this one that My Wedding Reception Ideas (myweddingreceptionideas.com) have created is probably the best.
Not only is it comprehensive, but it is interactive, as in you can tick the radio buttons on the pdf via your computer or smart phone/tablet and save it to keep up with what you have done and what you still have to do.
