Term for old folk sayings, mostly in rhyme form, about the weather and the consequences for agriculture, usually drastically formulated as positive or negative. Predictions are made on the basis of past experience. They have been created over centuries by closely observing natural phenomena and have been passed on from generation to generation. The predictions often refer to a so-called Lostag. Lost days (also known as lurtage) are fixed days in the calendar which, according to old folk belief, enable forecasts to be made about the weather conditions in the following weeks, months and, more rarely, the coming year, determine the most favourable time for various agricultural activities (such as sowing or harvesting) and also allow forecasts to be made about the expected harvest.
