Potato Week and Other Strangely Unique Holidays in the Nordic Countries

No Nordic government has ever declared an official Potato Week. That is the least interesting fact in this story. The more interesting one is that when the region’s odd holidays are traced to their origins, they keep ending in the same few places: a medieval legend, a mishearing, a trade dispute, a bakers’ trade association, or a university student society. The Nordic countries seem to hold that if a day is going to exist, it should at least come with a backstory.

The tidiest way to see this is to follow a hypothetical traveler through one year. The traveler has unlimited leave, a sizeable bank account, a strong constitution, and no plans to lose weight.

The year at a glance

Stop 1: Stockholm, 4 October

The year begins with a holiday that has a project leader. The Home Baking Council created Cinnamon Bun Day in 1999, and Le Petit Journal’s Stockholm edition credits Kaeth Gardestedt with launching it for the council’s 40th anniversary. Birgit Nilsson Bergström, the project leader, told SVT the idea was to give autumn something pleasant to look forward to. By her figures, Swedes buy about three million buns on the day, and the date has since been printed in the almanac.

The Local is refreshingly frank about the arrangement. Sweden, it notes, never passes up a chance to honour its baked goods with a national day. A trade association invented a holiday to sell more flour and sugar, and the public liked it enough to make it permanent. Few advertising campaigns manage that.

Stop 2: Copenhagen, week 42 (the nordic countries tell time in weeks, which makes little sense to many)

The traveler flies south for the holiday that gives this article its title, and finds that the wording is slightly generous. Denmark introduced a potato holiday in 1899, set for week 42, so that schoolchildren could help with the harvest. Week 42 starts on 12 October this year, and it is still the traditional slot for the Danish autumn break.

Norway’s version is harder to date. Life in Norway says the potetferie (potato holiday)( began in the early twentieth century and lingered in some rural areas into the 1970s. A Norwegian genealogy blogger remembers it as two or three days off, probably begun after the Second World War when food was scarce. The writer’s older brother worked a neighbouring farm during it in the early 1960s. The Stavanger Chamber of Commerce supplies the scene: some farms had no tractor, so a horse dragged a potato collector across the field and children rushed to pick up what sprang loose. Sweden’s counterpart, the potatislov, is described by one travel site as dating to the late nineteenth century, though that claim leans on a single source.

Scotland did the same thing. Its tattie holidays began in the 1930s, and by 1949 about 49,000 children were taking part. The remarkable part is that the break outlived the labour. Almost nobody under fifty picks potatoes now, so the Nordic autumn break is a holiday named after a job that no longer exists. The week survived probably because parents had organised their year around it. Gilleleje Museum in North Zealand now runs a potato-creature workshop for the break, which is as close to an official Potato Week as the region gets.

Stop 3: Helsinki, 13 October

A short flight east lands the traveler in time for the holiday with the most ambitious mission statement. In 2010, students at the Aalto Entrepreneurship Society decided Finland needed a day devoted to failing. Society president Niklas Hamberg told Euronews that failure had been a real taboo in Finland, and that destigmatising it was part of getting young people to start companies. Yle’s report on the third edition in 2013 quotes chair Elina Uutela and organiser Janika Kallio, which suggests the project had acquired a committee by then.

Whether a society devoted to celebrating failure can be said to have succeeded is a question for the philosophers. As a holiday, it has certainly lasted. It falls on a Tuesday this year, 13 October, which is three days after this article was written.

Stop 4: Denmark, late winter

The traveler spends the dark months eating well and then returns to Denmark for Fastelavn, a pre-Lenten carnival whose name comes from a Low German phrase meaning the evening before fasting, according to the Copenhagen diocese. The signature game is slå katten af tønden, which translates to “hit the cat out of the barrel.” Wikipedia notes that the barrel tradition may have arrived with Dutch immigrants in the early 1500s, and that the cat was originally real. The barrel was broken open and the cat was allowed to escape, which is probably the most reassuring clause in the history of Danish carnival.

The winner became cat king, and one Danish account says the title came with a year’s exemption from taxes. It is arguably the best tax policy in Danish history, though uptake was limited by the cat requirement. Today the barrel holds candy and the cat is a drawing. Fastelavnsboller, the cream buns, are the one element present in every Nordic version.

Stop 5: Reykjavik, 1 March

Beer Day sounds like a joke until the history comes out. Iceland voted for prohibition in 1915. Spain then refused to buy Iceland’s fish unless Iceland also bought Spanish wine, which forced a partial retreat, and a second referendum repealed prohibition in 1933 by a narrow margin. Parliament kept beer illegal anyway, to appease the temperance movement, according to the Associated Press. Beer remained banned until 1 March 1989, 74 years after the original vote, while every other form of alcohol was legal.

VOA reports that Iceland’s 260,000 people bought 340,000 cans of the long-forbidden item on the first day. Brewer Sigurdur Snorrason, quoted by AP, remembers not being sure what to make of it, because the country knew so little about beer. The day is an observance rather than a day off, which tells its own story.

Stop 6: Sweden, 25 March

Waffle Day is the purest case of a holiday made by a mishearing. The Swedish name for the Annunciation feast is Vårfrudagen, “Our Lady’s Day,” and said quickly with a mouthful, it becomes Våffeldagen. The Local reports that Swedes simply went with it. A reader correction on that page points out that the feast marks the angel Gabriel’s visit to Mary, not her conception, which is celebrated on 8 December. A linguistic accident that Sweden decided, correctly, to treat as policy.

Stop 7: Iceland, April

The traveler returns to Iceland just in time for summer, though the weather has not been consulted. The old Icelandic calendar recognised two seasons, and summer began with the month Harpa, so the holiday falls on a Thursday between 19 and 25 April. Gift-giving on the day dates to the 16th century, well before Christmas presents became common.

The folklore is the best part. Folklorist Árni Björnsson, quoted in that piece, explains that frost on the eve counted as a good omen, because summer and winter had “frozen together.” That makes a cold, grim start to summer the lucky outcome, which suits a holiday that appears to depend on the weather disagreeing with it.

Stop 8: Naantali, 27 July

The year ends, appropriately, with a holiday about waking up. Finland’s Unikeonpäivä is tied to the legend of the Seven Sleepers of Ephesus. Wikipedia’s account says medieval households believed that whoever slept latest would be lazy all year, and was woken with water, sometimes by being thrown into a lake or the sea.

In Naantali, a town near Turku, the custom is now performed on a local celebrity, chosen each year and thrown into the harbour. Sources disagree on whether it happens at 7 a.m. or 8 a.m., which means the only open question in the entire affair is the time of the dunking.

Back to the potatoes

By the following October, the traveler has been thrown out of bed, frozen into summer, and lectured on failure, and the potato harvest is starting again. The pattern across all eight stops is that almost nothing here was imposed from above. A bakers’ trade association, a student society, a wine-for-fish trade dispute and an accidentally similar-sounding word did most of the work, and the public simply kept the results. For a region with a reputation for restraint, the Nordic calendar is generous with holidays that make no particular sense.

A note on dates

Several of these move with Easter or the weekday calendar, and school break weeks differ by municipality. Check local dates before planning a trip around any of them.
