Here is a comprehensive summary of the Farmers' Almanac article:

The Farmers' Almanac, an iconic American periodical published continuously since 1818, offers long-range weather predictions for the U.S. and Canada alongside calendars, full moon dates, folklore, and outdoor activity tips. Founded by David Young and Jacob Mann in Morristown, New Jersey, it has had just seven editors—including Ray Geiger (starting in 1933, the longest-serving) and Sandi Duncan, who became the first female editor in 178 years in 1994. Its weather forecasts, made up to two years in advance, rely on a secret "exclusive mathematical and astronomical formula" by the pseudonymous forecaster "Caleb Weatherbee," with publishers claiming 80–85% accuracy, though scientific analyses often show about 50%. Released each late August, the edition covers 16 months across 7 climatic zones, and it has expanded online since 1997, boasting over 1.2 million Facebook followers. In November 2025, the Almanac announced it would cease production after the 2026 edition due to "growing financial challenges," but it was promptly acquired by Farmers' Almanac LLC, led by Tim Konrad, which plans to relaunch it in March 2026. Following the heritage of Benjamin Franklin's Poor Richard's Almanack, it has blended practical weather wisdom with humor and tradition for over two centuries.
