A schedule, or timetable, was a list created for the purposes of managing one's time.
In 2266, the Karidian Company of Players had a tight schedule of performance dates for the play Macbeth that included stops at Planet Q and Benecia. Lenore Karidian offered to add a special performance for the crew of the USS Enterprise in exchange for passage. (TOS: "The Conscience of the King")
In 2366, Romulan defector Alidar Jarok claimed to have seen timetables for the completion of a Romulan base on the planet Nelvana III inside the Romulan Neutral Zone, though the USS Enterprise-D detected no base. (TNG: "The Defector")
In 2373, The Doctor created Doctor's Family Program Beta-Rho in order to simulate the experience of having a family, but his attempt was criticized by B'Elanna Torres, who noted the seemingly perfect nature of the members of the Doctor's family and told him that real-life wasn't like this. In order to gain a more authentic experience, The Doctor agreed to let her introduce a few random elements into the program, resulting in changes such as his son Jeffrey becoming rebellious and his daughter Belle playing sport he found too dangerous for her age, such as Parisses squares. In attempt to remedy the situation, he created a rigid family schedule, but it was rejected by his entire family, including his wife Charlene, due to the complete lack of input allowed to them.

In 2375, as Tom Paris and B'Elanna Torres suffered from low morale due the effects of the starless expanse that the USS Voyager was trapped in, Paris asserted that it did not matter when he started a fight with her, as she was angry 24 hours a day. He suggested that the two of them make a schedule, a "fight rotation," that it would optimize their resources, that he could start one and then she could start one. (VOY: "Night")
In 2376, Seven of Nine, a former Borg drone, found herself caring for four children who like herself had been liberated from the Borg Collective. She found their behavior unpredictable and had difficulty controlling them. In an attempt to bring order, she created a rigid schedule which included specific allotted times for "fun." Upon seeing the schedule, however, Chakotay told her that fun could not always be scheduled and that she was treating the children as if they were still Borg, that they needed to be able to express their individuality.
