A personal organizer, also known as a datebook, date log, daybook, day planner, personal analog assistant, book planner, year planner, or agenda (from Latin agenda – things to do), is a portable book or binder designed for personal management. It typically includes sections such as a diary, calendar, address book, blank paper, checklists, and additional useful information like maps and telephone codes. It is related to the separate desktop stationery items that have one or more of the same functions, such as appointment calendars, rolodexes, notebooks, and almanacs.
