Annual publications, more often simply called annuals, are periodical publications appearing regularly once per year. Although exact definitions may vary, types of annuals include: calendars and almanacs, directories, yearbooks, annual reports, proceedings and transactions and literary annuals. A weekly or monthly publication may produce an Annual featuring similar materials to the regular publication. Some encyclopedias have published annual supplements that essentially summarize the news of the past year, similar to some newspaper yearbooks.

An almanac is a regularly published listing of a set of current information about one or multiple subjects. It includes information like weather forecasts, farmers' planting dates, tide tables, and other tabular data often arranged according to the calendar. Celestial figures and various statistics are found in almanacs, such as the rising and setting times of the Sun and Moon, dates of eclipses, hours of high and low tides, and religious festivals. The set of events noted in an almanac may be tailored for a specific group of readers, such as farmers, sailors, or astronomers.
