Farmers' Almanac

Farmers' Almanac is an annual American periodical that has been in continuous publication since 1818. Published by Geiger of Lewiston, Maine, the "Farmers' Almanac" provides long-range weather predictions for both the U.S. and Canada. 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.
Each new year’s edition is released at the end of August of the previous year and contains 16 months of weather predictions broken into 7 zones for the continental U.S., as well as seasonal weather maps for the winter and summer ahead. 
In addition to the U.S. version, there is a Canadian "Farmers' Almanac", an abbreviated "Special Edition" sold at Dollar General stores, and a Promotional Version that is sold to businesses as a marketing and public relations tool.
History.
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 "Farmers’ Almanac" has had seven editors. Poet, astronomer, and teacher David Young held the post for 34 years starting from when he and publisher Jacob Mann first founded The Almanac Publishing Company in Morristown, New Jersey. Following Young’s death in 1852, astronomer Samuel Hart Wright became editor.
In 1933, Ray Geiger took over as the sixth editor of the "Farmers’ Almanac" and began what became the longest-running editorship in "Farmers’ Almanac" history. 
In 1994, Ray's son Peter became editor. Sandi Duncan is now Managing Editor with him. Sandi was the first female editor in 178 years to hold an editorial position.
In 1997, an online version was created at FarmersAlmanac.com. The Almanac has over 1.2 million followers on Facebook, and is also on Twitter, Instagram, Pinterest, TikTok and other social media sites.
Weather prediction.
Predictions for each edition are made as far as two years in advance. 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. Seasonal maps and summaries for each season are also shared in each new edition, as are forecasts for annual sporting events. Predictions cover 16 months, from the previous September (through December of the publication year).
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". The Almanac's forecaster is referred to by the pseudonym Caleb Weatherbee. According to the publishers, the true identity of the forecaster is kept secret to prevent them from being "badgered".
Accuracy.
Publishers claim that "many longtime Almanac followers claim that their forecasts are 80% to 85% accurate" on their website. Their website also contains a list of the many more "famous" weather predictions they have accurately forewarned of and like to point out that they have been predicting the weather longer than the National Weather Service. 
Most scientific analyses of the accuracy of "Farmers' Almanac" forecasts have shown a 50% rate of accuracy, which is higher than that of groundhog prognostication, a folklore method of forecasting. USA Today states that "according to numerous media analyses neither the Old Farmer's Almanac nor the Farmers' Almanac gets it right".
Notable articles.
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).
