Diary (stationery)

In stationery, a diary (UK and Commonwealth English), datebook, daybook, appointment book, planner or agenda (American English) is a small book contained a main diary section with a space for each day of the year with room for notes, a calendar.

Usually, various pages at the beginning and end contained various pieces of reference information, which may include maps and telephone codes, and pages for a short address book at the end.

The US Customs official definition of a diary is: "A book prepared for keeping a daily record, or having spaces with printed dates for daily memoranda and jottings; also applied to calendars containing daily memoranda on matters of importance to people generally, or to members of a particular profession, occupation, or pursuit".

A large variety of layout formats are sold, including: Often, as in the diary pictured above, weekend days are given less space than workdays.

Especially in diaries for children or young people, many are now branded for fictional characters, authors, recording artists or magazines.
