What is Prinsjesdag? Guide to Dutch September Traditions

Every year on the third Tuesday in September, the political heart of the Netherlands transforms into a vibrant spectacle of royal pomp, elaborate millinery, and critical economic announcements. Known as Prinsjesdag (Prince's Day), this unique day is both a majestic constitutional ceremony and a pivotal moment for anyone living, working, or studying in the Netherlands.

For expats, internationals, and Dutch language learners, Prinsjesdag offers a fascinating window into Dutch society, monarchical tradition, and parliamentary democracy. It marks the end of the Dutch summer holiday season and sets the stage for the country's national agenda for the coming year. In this comprehensive guide, we'll explore the history of Prinsjesdag, its most famous customs (from golden carriages to political statement hats), essential Dutch political vocabulary, and what the day means for your daily life.

What is Prinsjesdag? Origins and Significance

In official Dutch terms, Prinsjesdag is also referred to as Begrotingsdag (Budget Day). It is the ceremonial opening of the Dutch parliamentary year for the Staten-Generaal (the Senate and the House of Representatives), held annually in The Hague (Den Haag).

The name Prinsjesdag dates back to the 18th century. Originally, it referred to the celebration of the birthday of Prince Willem V on March 8. During the era of the Patriots (a democratic political movement in the late 1700s), celebrating the Prince's birthday was an act of loyalty to the House of Orange. In the 19th century, after the establishment of the Kingdom of the Netherlands, the name was colloquially transferred to the day parliament opened.

According to Article 65 of the Dutch Constitution, the state opening must take place on the third Tuesday in September. According to historical records on Prinsjesdag history, this specific day was chosen in 1887 to give parliamentarians sufficient time to debate and pass the national budget before the new fiscal year begins on January 1, while avoiding long travel disruptions for representatives coming from rural provinces.

The 5 Iconic Traditions of Prinsjesdag

Prinsjesdag combines centuries-old monarchical protocol with down-to-earth Dutch governance. Here are the five key elements you will see on the news or in the streets of The Hague:

1. The Royal Procession (De Koninklijke Stoet)

Shortly after midday, King Willem-Alexander and Queen Máxima depart from Noordeinde Palace in a horse-drawn ceremonial carriage, accompanied by members of the Royal Household, mounted police, and military honour guards. Traditionally, the King travelled in the historic Gouden Koets (Golden Coach), a gift from the citizens of Amsterdam in 1898. In recent years, due to historical debates surrounding colonial imagery on the Golden Coach, the King uses the Glazen Koets (Glass Coach), a stunning royal carriage built in 1826.

2. The Speech from the Throne (De Troonrede)

The procession arrives at the location of the joint session of parliament—traditionally the Ridderzaal (Hall of Knights) in the Binnenhof, though temporary locations such as the Koninklijke Schouwburg (Royal Theater) are used during major restorations. Here, the King delivers the Troonrede. While read by the monarch, the speech is written by the Prime Minister (minister-president) and cabinet ministers. It reviews the state of the nation and outlines the government's primary legislative and financial priorities for the coming year.

3. The Little Budget Suitcase (Het Koffertje)

Perhaps the most famous visual symbol of Dutch fiscal policy is a simple leather briefcase bearing the text: "Derde Dinsdag in September". Carried by the Minister of Finance (Minister van Financiën), this briefcase contains the Miljoenennota (the National Budget memorandum) and the Rijksbegroting (the state budget). The tradition began in 1947, inspired by the British Budget Day tradition, and has become a beloved media moment.

4. The Parade of Hats (De Hoedjesparade)

Prinsjesdag has developed an unintentional yet famous fashion tradition known as the Hoedjesparade (Parade of Hats). Female parliamentarians, ministers, and invited guests wear striking, elaborate hats. What started in 1977 when MP Erica Terpstra wore a flamboyant hat to brighten up the sea of grey political suits has evolved into a national spectacle. Today, many politicians use their hats to make subtle—or bold—political, environmental, or social statements.

5. The Balcony Scene (De Balkonscène)

After the Speech from the Throne, the Royal Family returns to Noordeinde Palace. At around 2:00 PM, they appear on the palace balcony to wave to thousands of cheering citizens waving orange flags, an event known as the Balkonscène.

Other Dutch Traditions to Watch in September and Early Autumn

Prinsjesdag is the centrepiece of Dutch September culture, but the transition from late summer to autumn brings several other cultural customs that help you integrate into life in the Netherlands:

Open Monumentendag (Heritage Days)

Held on the second weekend of September (just before Prinsjesdag), Open Monumentendag allows the public free access to thousands of historical buildings, monuments, castles, and private canal houses across the country that are usually closed to visitors.

The 'Back to Normal' Mentality

In early September, Dutch workplaces, sports clubs, and schools return to their strict agendas after the summer break. Dutch colleagues will often exchange stories about surviving unique Dutch cultural rituals and holidays before diving straight into the busy autumn work season.

Preparations for Autumn Feasts

September also builds excitement for regional historical commemorations, leading directly into October traditions like historic celebrations like Leidens Ontzet, where communities celebrate local heritage with parades, music, and seasonal food.

How to Experience Prinsjesdag Like a Local

Want to immerse yourself in the Prinsjesdag experience? Here are a few practical ways to take part:

1. Visit The Hague in Person: You can stand along the route of the royal procession (such as along the Lange Voorhout or near Noordeinde Palace). Arrive early—by 10:00 AM—to secure a good viewing spot near the palace gates.
2. Watch the Live Broadcast: The Dutch public broadcaster (NOS on NPO 1) broadcasts live coverage starting around 12:30 PM. It is fantastic listening practice for intermediate (B1–B2) Dutch learners.
3. Follow the General Debates: In the two days following Prinsjesdag, watch the Algemene Politieke Beschouwingen on television or online to hear party leaders debate the government's plan. It is a masterclass in Dutch debate culture and political idioms.
4. Discuss the News in Dutch: Try asking your Dutch colleagues: "Wat vind jij van de plannen op Prinsjesdag?" (What do you think of the plans on Prince's Day?)—it is an instant conversation starter at the office coffee machine.
