The periodical also provides calendars and articles on topics such as full moon dates, folklore, natural remedies, and the best days to do various outdoor activities.

[2][3][4] Founded in 1818, the Farmers’ Almanac mixes a blend of long-range weather predictions, humor, fun facts, and advice on gardening, cooking, fishing, conservation, and other topics.

The U.S. retail edition of the Farmers' Almanac contains weather predictions for 7 U.S. climatic zones, defined by the publishers, in the continental United States, broken into 3-day intervals.

The Farmers' Almanac will only state publicly that their method is an "exclusive mathematical and astronomical formula, that relies on sunspot activity, tidal action, planetary position (astrology) and many other factors".

[10] Most editions of the Farmers' Almanac include a "human crusade," advocating for a change in some accepted social practice or custom.

Previous crusades have included: "How Much Daylight Are We Really Saving," a recommendation for a revised Daylight Saving Time schedule (2007); "Why is Good Service So Hard to Schedule," recommending that service providers offer more specific timeframes when scheduling home visits (2006); "A Kinder, Gentler Nation," urging readers to exercise more common courtesy (2003); "Saturday: The Trick to Making Halloween a Real Treat," advocating that the observance of Halloween be moved to the last Saturday in October (1999); "A Cure for Doctors' Office Delays," demanding more prompt medical service and calling for a "Patients' Bill of Rights" (1996); and "Pennies Make No Sense," which sought to eliminate the penny, and to permanently replace the dollar bill with less costly-to-produce dollar coins (1989).
