21 December 1872

21 December 1872 is the decisive date in Phileas Fogg’s wager: by a quarter before nine that evening, he must be back in the same room of the Reform Club in London, or forfeit £20,000. The deadline turns his eighty-day itinerary into a public test of precision, while the eastward journey’s hidden gain of a day makes the calendar itself part of the outcome.

The wager and its deadline

On 2 October 1872, amid a discussion of whether the world could be circled in eighty days, Fogg accepted the challenge without allowing for bad weather, contrary winds, shipwrecks, railway accidents, or other disruptions. When his companions raised the possibility of interrupted railway service and attacks on passengers, he maintained that the unforeseen did not exist. He treated the journey as a minimum-time calculation that could be met through exact transfers between trains and steamers.

Fogg staked £20,000 deposited at Barings Bank, half his fortune, and specified the terms precisely: he would be back in the Reform Club on Saturday, 21 December, at a quarter before nine in the evening. A cheque was given for the stake, and the six participants signed a memorandum. Fogg explained that he might need the other half of his fortune to carry out the journey. His opponents were troubled less by the size of their own stake than by the severity of the conditions they had accepted.

The date was anchored to a stated departure and a fixed return, not just to the broad promise of travelling around the world. Fogg and his servant left by train on the evening of 2 October, and he later confirmed the same deadline: eighty days, ending at 8:45 p.m. on 21 December. The wager therefore made punctuality measurable down to the hour and minute.

A timetable under pressure

Fogg’s confidence in calculation was tested by the very contingencies his companions had named. His schedule depended on moving from trains to steamers and back again with almost mathematical exactness. The book’s account of the final Atlantic crossing makes the pressure concrete: the Henrietta might cover the 3,000 miles from New York to Liverpool in the nine days between 12 and 21 December, but only if the sea remained manageable, the wind did not turn east, and neither the vessel nor its machinery suffered an accident. Even a successful crossing could leave Fogg facing further difficulties on arrival.

That timetable contrasts with Fogg’s otherwise controlled habits. On the morning the wager began, he had dismissed a servant because the shaving water was 84 degrees Fahrenheit rather than the required 86. He sat watching a clock that displayed seconds, days, months, and years, and normally left his home at half-past eleven for the Reform Club. The exacting domestic routine establishes how naturally he treats time as something that can be regulated; the wager extends that discipline across oceans and railways, where circumstances cannot be controlled so simply.

The date and the gained day

The deadline acquires its final significance through a discrepancy between the date Fogg believes he has reached and the date in London. On arriving in London, he thinks it is Saturday, 21 December, but it is actually Friday, 20 December—the seventy-ninth day since his departure. He has travelled constantly eastward and, without realizing it, gained a day. Travelling in the opposite direction would have lost one.

The explanation is geographical and cumulative. As Fogg travelled east, the sun passed the meridian at different times along his route; the local days diminished by four minutes for each degree crossed. Around the earth’s 360 degrees, those differences amount to twenty-four hours. Fogg has therefore seen the sun pass the meridian eighty times while his friends in London have seen it pass only seventy-nine times. The date does not change the terms of the wager; it changes how much time Fogg has actually used to meet them.

Significance

The date is both a strict contractual limit and the point at which Fogg’s faith in precision is exposed to a larger system of time. His habits and calculations make the deadline appear absolute, but the eastward journey produces a day he has not counted. The ending makes the calendar’s global logic decisive: Fogg wins the £20,000 wager because his circuit has taken one day less than he believes, and 21 December remains the promised deadline even as his mistaken reckoning nearly obscures his success.
