Schedule Fanatic

""Some part has malfunctioned and must be replaced. It will require at least an hour. This sends Effie into a state. She pulls out her schedule and begins to work out how the delay will impact every event for the rest of our lives.""

- Catching Fire

This is a character who has to do everything according to precise schedule, every day of their lives. You could set your watch by them. This is often portrayed as being unhealthy and/or tied in with some kind of mental condition. Obviously, watching someone go about things the same way for the entire story would get very dull, so the plot generally forces them to break this schedule at some point.

See also Clock King, someone who knows not only their own schedule but also everyone else's, and Super OCD, which this can be a part of.

Comic Books

 * In a Looney Tunes comic book story, Elmer Fudd becomes fanatical about following schedules after reading a self-help book: "I made dinner, then I thwew it out and washed the dishes. I wish I'd wemembered to put 'Eat dinner' on the wist. I'm hungwy, but I'm on schedule!" Bugs Bunny, naturally, exploits Elmer's obsession by switching his schedule with one that requires him to do bizarre and humiliating things.
 * Skalman from Bamse is a very meticulous man (erh, anthropomorphic turtle) who loves eating and sleeping almost as much as he loves reading and thinking. His own favorite invention is his "food-and-sleep-alarm-clock" who calls many times a day to announce time for various snacks and naps (presumably to make the sleeping and eating more efficient). He is so disciplined to it that a "naptime" signal can call him to sleep in the middle of, say, fighting in a tournament. Likewise, once he starts sleeping, it is almost impossible to wake him up. When he once felt he had to work non-stop on an invention (being deeply distressed) he turned off the clock and didn't sleep or eat until done (when he collapsed).

 * Clockwise. Just...Clockwise. Brian, played by John Cleese, is a strictly punctual headmaster who holds everyone else to his own exacting standards. The whole plot of the movie is how a misunderstanding leads to him missing his train to an important event and how his life slowly unravels as he tries desperately to get there on time. In the end Brian was chronically late and disorganized when he was younger, so his insane devotion to punctuality is likely overcompensation.

 * Time Man, one of the two new Robot Masters from Mega Man Powered Up, is obsessed with schedules, to the point where he berates others for being late or slowing him down (ironic, in that his special ability is to slow down time).
