Early almanacs were permanent tables of the apparent motions of the sun and moon, from which astronomical data for any year could be calculated. In the 15th cent. almanacs began to be prepared for definite periods, such as 10 or 30 years, and in the 16th cent. for the year. From this period astrological and meteorological predictions were also included, alongside other information. (OED)
