I just bought a speedy day/date or triple calendar off Ebay. Perhaps, enough said. Anyway, the month does not change over until the date hand passes from the sixth to the seventh. It should change over when the date hand passes from the thirty-first to the first right? Is this a major problem? In other words, is this going to cost major bucks to fix? Or, should I just return it to the seller and get my money back? Any input from you seasoned vets wold be appreciated. Thanks.
