Or maybe not at all, because I suspect the address books were printed at the end of the old year, given that they also, as the title suggests, contain a calendar, and then as a last page they got the "changes during printing" one. So my guess is that Lehndorff probably moved for the first time before the February 1759 wedding, because the book, including the "during printing" page, should have been finished by then if it was to be used for the year. And then he moved again in 1759, and early enough for the new address to be included in the 1760 calendar regularly.
