Kafka kept a schedule that should have been impossible. He held down a full-time job as a lawyer at the Workers' Accident Insurance Institute in Prague, six days a week in the early years and later five, starting at 8:30 in the morning and running until 2:30 in the afternoon. He came home, ate lunch with his family, slept until the early evening, ate dinner, walked, and then sat down at his desk around eleven at night and wrote until one, two, or three in the morning. Then he slept for a few hours and did it again. He produced The Metamorphosis, most of The Trial, large sections of The Castle, and most of his short fiction on that schedule, which amounts to the most productive use of the worst writing hours in literary history.

The usual framing of Kafka as a tortured clerk who happened to write strange stories on the side gets the relationship backwards. Kafka was a working writer who happened to have a day job. The day job was the problem he spent his whole adult life trying to write around, and the routine he built was the compromise he arrived at with himself after years of experimentation. It almost destroyed his health, and he knew it would, and he did it anyway because the alternative was to stop writing.

Profile

The Routine at a Glance

Wake Time
Around 7:30 in the morning, in order to be at the insurance office by 8:30.
Writing Location
His parents' apartment in Prague, where he lived for most of his adult life. Often a small, cramped bedroom adjoining the main family rooms, which meant writing while the rest of the household slept on the other side of a thin wall.
Daily Output
Variable, and often agonized over in his diaries. During his most productive bursts, he could write entire stories in one overnight sitting. He wrote The Judgment in a single night in September 1912, from ten in the evening to six in the morning.
Tools
Pen and ink, and a plain notebook. His handwriting was tight and careful, and he often continued manuscripts for months in the same notebook without crossing out much.
Famous Ritual
The late afternoon nap. After lunch with his family, Kafka slept from around 3:30 until 7:30 in the evening. The nap was non-negotiable. It was the only way he could be awake for the writing hours that came after midnight.
Books Written This Way
The Metamorphosis, The Judgment, The Trial (unfinished), The Castle (unfinished), Amerika (unfinished), and most of the short stories collected in A Country Doctor and A Hunger Artist.

The Day Job

Kafka's job at the Workers' Accident Insurance Institute gets treated as a biographical footnote, which misses how thoroughly it shaped both his writing time and his writing material. He was a trained lawyer who handled industrial accident claims, not a minor clerk pushing paper. That meant he spent his days reading case files about workers who had lost fingers in machinery, fallen from scaffolding, or been crushed by lumber. He toured factories and wrote technical reports about workplace safety. The reports were apparently very good. He was promoted several times and was well-regarded by his superiors, who had no idea their reliable young lawyer was also the author of The Metamorphosis.

The bureaucratic nightmare world of The Trial and The Castle is usually read as pure invention. It was also, in large part, transcription. Kafka spent thirty hours a week inside an actual institution of opaque procedures, infinite paperwork, and authority figures whose decisions couldn't be appealed, and he was taking notes, consciously or not, the whole time. The surreal logic of his fiction is the logic of insurance bureaucracy rendered at a slightly higher intensity. The Castle didn't have to be invented. Kafka worked there until two thirty every afternoon.

What the day job stole from him was the morning, which most writers agree is the best writing time. What it gave him was material and a steady income that let him live with his parents in relative comfort while he wrote. The trade was not one he ever stopped resenting. His diaries and letters are full of fantasies about quitting the office and writing full-time, which he never did. The routine he built was the compromise he arrived at after accepting that he was going to keep the job, because the financial independence of keeping it was, for him, worth more than the morning hours it cost.

The Nap

The strangest part of the routine, and the one that unlocks everything else, is the four-hour afternoon sleep. Kafka came home from the office at around 2:30, ate lunch with his family, and then went to bed from roughly 3:30 until 7:30. Four hours. In the middle of the day. This is not a nap in any normal sense of the word. It is a second night of sleep grafted onto the afternoon, and it was the only way the whole schedule hung together.

You can't stay awake from 7:30 in the morning until 3 in the morning without giving yourself up to exhaustion. Kafka figured out, through trial and error, that he could split his sleep into two sessions and stay functional for both of his working lives. Four hours after lunch, four or five hours after the writing ended, and he could be back at the insurance office by 8:30 the next morning. The total sleep is not unreasonable for a young adult. The timing is what's unusual, and it's the structural decision that made the rest of the routine possible.

"Time is short, my strength is limited, the office is a horror, the apartment is noisy, and if a pleasant, straightforward life is not possible, then one must try to wriggle through by subtle maneuvers."

Sleep researchers now talk about biphasic sleep and segmented sleep as patterns that were historically common before industrial lighting compressed human rest into a single nightly block. Kafka had no access to any of that research. He was solving a problem, which was that he needed the last four hours of the day to himself and he was not going to get them any other way. The nap was the price of admission. Without it, the writing hours would have been useless, and the writing hours were the whole point.

Midnight to Dawn

The actual writing happened between about eleven at night and one or two in the morning, sometimes later when a story was running. This is brutal time for prose work. By eleven, most people are winding down. Kafka was winding up. He'd had his nap, he'd had a walk, he'd had dinner with his family, and now the apartment was quiet and his mother and father and sisters were all in their beds, and he had maybe three hours before his own body would give out on him.

The constraint produced a specific kind of writing. Kafka's prose is famously compressed and strange, full of long unbroken paragraphs and sentences that seem to follow a dream logic, and I think some of that comes directly from the hours he was writing in. At midnight, the internal editor is quieter. The waking mind is starting to blur with the part of the brain that produces dreams. Images come up that wouldn't come up at three in the afternoon. The insurance lawyer's logical habits relaxed just enough to let the subconscious material through. Read The Metamorphosis with that in mind and you can feel the hours it was written in. A man wakes up as a giant insect, and the story treats it with the calm acceptance of a dream that is already halfway over before you realize how strange it is.

The most famous night of Kafka's writing life was September 22 to 23, 1912, when he sat down at ten in the evening and wrote The Judgment in a single uninterrupted session that ended at six in the morning. He recorded the experience in his diary the next day with something close to astonishment. The story came out fully formed, in order, almost without revision. He said he felt as if he were being dragged forward by the story, as if the writing were happening to him rather than by him. This is the kind of experience that only occasionally visits a writer, and when it does it almost always visits them at the end of the day, when they're tired enough that the usual defenses have come down. Kafka's routine was designed around the hope of making that night happen more often than chance alone would provide.

The Famous Letter

Almost everything we know in detail about Kafka's daily schedule comes from a single document. On November 1, 1912, Kafka wrote a letter to Felice Bauer, the woman he was then in the early stages of courting by mail, and in the letter he laid out his entire daily routine in step-by-step detail. He was doing it to explain to her why he had so little time, why his letters were late, and why their eventual life together was going to be complicated by the fact that he needed those small hours of the night for his writing. The letter runs for several paragraphs and reads like a timetable.

Eight thirty to two thirty at the office. Lunch until three thirty. Sleep until seven thirty. Exercise, then dinner with the family. Then, starting around ten or eleven at night, writing for as long as his strength held out. He tells her that he sometimes works until one, sometimes until three, sometimes until six in the morning when a story is running. He tells her that he knows this is not a life that can be shared with anyone in a normal sense. He is, essentially, warning her. He is also, without meaning to, leaving the single best primary source we have on how a working writer with a day job actually organized his hours in the early twentieth century.

Reiner Stach, whose three-volume biography is the definitive work on Kafka, treats the Felice letters as the central document of Kafka's life, and the November 1 letter is one of the most quoted passages in the entire correspondence. Kafka's relationship with Felice eventually collapsed, partly because the schedule described in that letter was incompatible with any conventional marriage. The routine he was defending in the letter was the same routine that produced the fiction we still read a century later. He chose the fiction, and he paid for the choice in loneliness.

Sources

The primary source for Kafka's routine is his November 1, 1912 letter to Felice Bauer, reprinted in Letters to Felice (Schocken Books, English edition edited by Erich Heller and Jürgen Born, 1973). Kafka's diaries, available in the Schocken edition edited by Max Brod and in the more recent unexpurgated translation by Ross Benjamin (2022), contain many additional references to the schedule and the September 1912 night of writing The Judgment. Reiner Stach's three-volume biography Kafka: The Decisive Years, Kafka: The Years of Insight, and Kafka: The Early Years (Princeton University Press) is the definitive modern account and reconstructs the daily routine in considerable detail. Mason Currey's Daily Rituals contains a condensed summary with citations.

What You Can Steal

Kafka's schedule is extreme and most of it shouldn't be copied literally. There is still a lot to learn from it if you read it as a case study in what a working writer with a day job is actually willing to do.
