Calendar (stationery)
Alongside their practical uses, calendars have taken on a decorative purpose, offering an easy way to introduce regularly changing artwork to a space, and have even influenced art and sexuality by popularizing the pin-up style.The modern calendar evolved alongside others such as almanacs, which collected religious, cultural, meteorological, astronomical and astrological information in a table format; practica, which gave astrological predictions for the year ahead; and diaries, which were for personal and professional use.Common subjects include landscapes, automobiles, wildlife, male or female models and popular culture.Businesses frequently give wall calendars branded with their names and contact information away for free to customers as promotional merchandise.Some are essentially pornographic in nature, but a more recent evolution is calendars featuring people in comic situations and published for charity.
