...and the dates

21st century digital calendar

A calendar was any system of measuring long periods of time, including days, months, and years. In Human culture, the term also referred to a series of visual charts, usually representing months, used to keep track of such calendar.

In 1930, the Twenty-First Street Mission had a calendar hanging on the wall. (TOS: "The City on the Edge of Forever")

In 1947, a pin-up calendar was hanging on the wall of the Roswell US Army Air force base. (DS9: "Little Green Men")

A digital calendar was present on the wall of Sanctuary District A's processing center in 2024. After Commander Benjamin Sisko and Doctor Julian Bashir were inadvertently sent back in time due to a transporter accident in 2371, Sisko noted the date on the wall calendar to be August thirtieth, two days before the beginning of the Bell Riots. (DS9: "Past Tense, Part I")

The script for "Past Tense, Part I" describes the scene as follows; "While Bashir and Vin are talking, something catches Sisko's eye. It's a digital WALL CALENDAR displaying the date '8-30-24.' Sisko looks at the calendar for a long beat, then looks outside." [1]

In 2369 the Bajoran criminal Ibudan saved his meetings and activities in a personal calendar file on a Bajoran transport. Odo reviewed these notes. (DS9: "A Man Alone")

In 2376, Neelix proposed a riddle to Tuvok while the two were on an away mission: an ensign was stranded on an uninhabited moon, without food, and all he had was a calendar. How could he survive? Eventually, Tuvok came to the "illogical" conclusion that the ensign could survive by eating the "Sundays," though the original answer was that he had "feasted on the dates." (VOY: "Riddles")
