On one Monday each spring, the most orderly country in Europe suspends its usual rules and turns the entire nation into a street party.
The dress code is orange. The flea markets are everywhere. The canals are too full of boats to navigate. And there is nowhere on Earth quite like it.
King’s Night: 26 April (Sunday evening)
King’s Day: 27 April, Monday (National holiday)
King’ Age in 2026: 59 (Born 27 April 1967)
Dress Code: Orange (Mandatory by tradition)
Holiday Since: 1885
Originally Princess’s Day
On 27 April 2026, a Monday, the Netherlands will do what it does once a year and has been doing in one form or another since 1885: it will turn entirely, gloriously, unstoppably orange.
Not a corner of the country will be unaffected. Not a canal city will be quiet. This is King’s Day – Koningsdag – and it is one of the most extraordinary mass celebrations on Earth.
King’s Day in 2026 falls on Monday 27 April – the 59th birthday of King Willem-Alexander, who became the first Dutch king in 123 years when his mother Queen Beatrix abdicated in 2013.
The celebrations begin the previous evening on King’s Night, 26 April, when the country warms up with concerts, DJ sets, and outdoor parties across Amsterdam, Utrecht, Rotterdam, and dozens of other cities. By midnight, any distinction between party and preparation has dissolved completely.
What makes Koningsdag unique among national celebrations is a combination of three things that rarely coexist: genuine national enthusiasm, a tradition of complete informality, and a legal framework that, for one day only, suspends normal commercial rules and allows anyone to sell anything on any street without a permit.
The result is a celebration that simultaneously functions as a block party, a flea market, a boat festival, a music concert, and a collective act of orange-coloured national pride – all at once, across the entire country.
141 Years of Orange: A Holiday That Has Evolved for Over a Century
The holiday’s origins reveal something interesting about the Dutch relationship with monarchy. In the 1880s, the liberal government of the Netherlands sought a way to build national unity around a royal family that was not universally loved.
Their solution was elegantly pragmatic: instead of celebrating the unpopular King William III, they created a holiday around his four-year-old daughter – Princess Wilhelmina, who was charming, non-controversial, and the heir to the throne.
The first Prinsessedag (Princess’s Day) was celebrated on 31 August 1885, her fifth birthday.
1885: Princess’s Day – the origin
The first holiday, celebrating five-year-old Princess Wilhelmina. Bands played simultaneously at 28 locations across The Hague, specifically to ensure even the poorest parts of the city were included.
1890: Queen’s Day – first edition
Wilhelmina ascends the throne aged 10. The holiday becomes Koninginnedag (Queen’s Day), celebrated on 31 August – her birthday.
1940-1945: Banned under German occupation
During the Nazi occupation, Queen’s Day celebrations were forbidden. Members of the Orange Committees that organised the holiday destroyed their records out of fear of German reprisals. The tradition resumed immediately after liberation.
1949: Moved to 30 April
Queen Juliana ascends; the holiday moves to her birthday. Later, Queen Beatrix keeps 30 April out of respect for her mother rather than switching to her own January birthday – wisely noting that outdoor celebrations in January were impractical in the Netherlands.
2013-2014: King’s Day is born
Queen Beatrix abdicates on Queen’s Day 2013. Her son Willem-Alexander becomes the first Dutch king in 123 years. From 2014, the holiday moves to 27 April (his birthday) and is renamed Koningsdag.
Oranjegekte: The Traditions Behind the Orange Madness
The Dutch call it oranjegekte – “orange madness” – and the description is accurate. The colour orange has no presence in the Dutch national flag (which is red, white, and blue), but it is the colour of the royal House of Orange-Nassau – the family that has held the throne since the early years of the Dutch Republic.
On King’s Day, the flag gets an additional orange pennant called a wimpel, and the rest of the colour requirements are handled by approximately 17 million people wearing everything from tasteful orange accessories to full head-to-toe costumes, orange wigs, and orange face paint.
Wear Orange – All of It
The dress code is not a suggestion. It is how you signal that you are part of this – locals and visitors alike. The creativity of the Dutch interpretation of “wear orange” is remarkable: vintage jackets, handmade outfits, orange crowns, orange sunglasses, orange-tipped dogs. Personality counts as much as quantity.
Vrijmarkt – The Free Market
King’s Day is the only day in the Netherlands when anyone can sell anything on any street without a permit and without paying VAT. The result is a nationwide flea market covering entire city centres. Children set up blankets to sell toys, books, and handmade treats to earn pocket money. Vintage finds, secondhand treasures, and handmade crafts line every pavement. In Amsterdam alone, hundreds of thousands of people buy and sell throughout the day.
Canal Flotilla
Amsterdam’s canals become the most cheerful traffic jam in the world. Hundreds of boats – decorated, blasting music, packed with people dancing – fill the waterways to capacity. The canal parade is entirely spontaneous and entirely uncoordinated, which somehow makes it more impressive. Renting a boat for the day is the premium King’s Day experience; watching from a bridge is the free alternative, and barely less spectacular.
Music Everywhere
Every public square becomes a stage. Street musicians, brass bands, DJs, and children’s performers cover every corner of every city. In Amsterdam, major festivals run simultaneously: Kingsland Festival, Loveland Burst, and Oranjebloesem are among the biggest, featuring international lineups. But the real music is the city itself.
Het Wilhelmus – Spontaneously
The Dutch national anthem, one of the oldest in the world, a poem written in 1574 describing William of Orange’s fight for the Dutch people, breaks out spontaneously at various moments throughout the day. It is a reminder that underneath the party is something genuinely felt.
Traditional Dutch Games
Alongside the flea markets and concerts, traditional Dutch games take place throughout the day – bite-the-cake (koekhappen), sack races, and the famously surreal tradition of throwing toilet bowls in some municipalities. The silliness is intentional and beloved.
“Interestingly, orange isn’t a common color in everyday life in the Netherlands, which makes its sudden appearance on King’s Day all the more striking. Walking through Amsterdam on April 27 feels like stepping into a massive, orange-hued festival where everyone is united in the same tradition.”

Beyond Amsterdam: Where to Be on King’s Day 2026
Amsterdam is the obvious answer – and for good reason. The combination of historic canal architecture, the density of events, and the sheer number of participants makes it the global reference point for Koningsdag.
But it is also the most crowded, the most expensive to stay in, and the hardest to navigate. Several alternative cities offer celebrations that are equally authentic and considerably less overwhelming.
Amsterdam: The Classic
Non-negotiable for first-timers. Vondelpark for families and the vrijmarkt; the Jordaan neighbourhood for the canal flotilla and local atmosphere; Leidseplein and Rembrandtplein for major music stages. Plan to walk everywhere – the centre closes to traffic entirely. Arrive the evening before to experience King’s Night and find your feet before the Monday crowds arrive.
Utrecht: The Cultural Choice
Many Dutch people argue Utrecht is actually more fun than Amsterdam on King’s Day – smaller, more coherent, with the Dom Tower as a backdrop and the canal-side terraces of the Oudegracht providing a spectacular setting. Five main squares host events: Domplein, Lucasbolwerk, Mariaplaats, Neude, and Janskerkhof. King’s Night here is one of the finest in the country.
Rotterdam: Modern Energy
Rotterdam’s King’s Day has its own character – the city’s bold modern architecture makes an unlikely but striking backdrop for a sea of orange. Large-scale electronic music festivals, waterfront events, and the Markthal area create a celebration that feels distinctly 21st-century. Less tourist-heavy than Amsterdam, more Rotterdam-resident-heavy, which is a significant improvement.
Haarlem, Leiden, Delft: Quieter Equally Festive
All three of these smaller cities offer genuine Koningsdag celebrations – vrijmarkts, canal decorations, local music – without the crowds that make central Amsterdam feel like a compression chamber. Haarlem is 20 minutes from Amsterdam by train; Leiden and Delft are easy day trips from Rotterdam. All three are beautiful in their own right.
The King Himself – Where He’ll Be
One of the distinctive features of Dutch royal tradition is that the King and Queen Máxima actually leave the palace and spend King’s Day in a different city every year.
They walk through crowds, join celebrations, watch children perform, and participate in the vrijmarkt. In recent years, Eindhoven, Maastricht, and Amersfoort have been the chosen locations.
The 2026 destination had not been officially confirmed at time of writing – watch the Royal House’s official announcements for the reveal, which typically comes a few months before. Wherever they go, that city gets an additional dimension of celebration and national television coverage.
What to Eat and Drink
King’s Day has its own distinct food and drink culture – not elaborate, but deeply specific.
Tompouce
The iconic King’s Day pastry – a custard cream slice with bright orange fondant icing on top. The icing, normally pink on other days, turns orange for the holiday. Found at every bakery and most street stalls throughout the week.
Oranjebitter
A traditional orange-colored bitter liqueur, raised in toast to the King. The name means “orange bitter.” It is slightly sweet, slightly herbal, and almost exclusively consumed on this one day of the year.
Haring (Herring)
Raw Dutch herring, held by the tail and lowered into the mouth, is a year-round Dutch street food that features prominently at King’s Day stalls. An acquired taste, and genuinely delicious if you can get past the presentation.
Stroopwafels & Poffertjes
Stroopwafels (waffle cookie sandwiches filled with caramel syrup) and poffertjes (tiny Dutch pancakes dusted with powdered sugar) are the sweet street staples of every King’s Day flea market. Children selling them on blankets for pocket money is a specific tradition.
Surviving the Orange Chaos: What to Know Before You Go
King’s Day 2026 is on Monday 27 April – a regular working day turned national holiday. King’s Night (Koningsnacht) begins on the Sunday evening of 26 April and is the official warm-up. Most international travelers arrive over the weekend to be in place before the main event. Book accommodation for 25-27 April at minimum.
Transport
The centre of Amsterdam closes to cars entirely on King’s Day. Buses and trams in the city centre run on significantly altered or shortened routes to avoid the crowds.
Extra train services operate to bring people home from celebrations, but central stations are extremely crowded by late afternoon.
The Dutch solution is the bicycle – if you can hire one for the day (book in advance), you will navigate better than any other mode of transport. Walking is the only real alternative in the densest areas.
Accommodation
King’s Day is one of the busiest nights of the year in Amsterdam, Utrecht, and Rotterdam. Hotel prices can triple or quadruple compared to normal April rates.
Book 3-4 months ahead at minimum. If you’re flexible on location, staying in Haarlem or a town outside Amsterdam and commuting in is a legitimate strategy – the train journey from Haarlem is 20 minutes and costs a few euros.
Safety and practicalities
King’s Day is notably peaceful for an event of its scale. Pickpocketing is the primary concern – keep valuables in front pockets or money belts in densely crowded areas.
The canal flotilla creates obvious drowning risks for the enthusiastic and the very intoxicated; stay away from canal edges after dark. Portable phone chargers are essential – battery drain is severe on a day this photographed.
There is a specific pleasure in watching an entire country do something together – not because they are required to, but because they genuinely want to.
King’s Day in the Netherlands is that pleasure, scaled to 17 million people and saturated in a colour that, for 364 other days of the year, you would barely notice in a Dutch street.
On the 27th of April, it is everywhere. And so, if you are wise, will you be. Fijne Koningsdag!
