The Four-Day Week Around the World

The four-day school week is not only an American story - but abroad it usually means something different. In the United States it is largely a rural, budget-and-staffing adaptation. In the one country where a four-day school week is genuinely mainstream - France - it grew from a cultural tradition and debates about children's fatigue, and it applies nationwide rather than district by district.

France: la semaine de quatre jours

For France's public primary schools, the four-day week is about how the week is arranged, not about compressing a rural district's costs. Its recent history is a striking example of policy instability:

2008: A reform under the Sarkozy government ended Saturday-morning class and set the primary week at four days (no school on Wednesday or Saturday). Within a year or two, the large majority of schools were on a four-day week.

2013: The Peillon reform ("rythmes scolaires") moved primary schools to a 4.5-day week, adding Wednesday morning, arguing that four long days were tiring for young children. It proved unpopular with many mayors, who bore the cost of the added activities, and with many parents.

2017: A decree of 27 June 2017 allowed local communes to return to the four-day week, and a large share did so immediately. The four-day week again became the de facto norm for French primary schools, where it remains for the large majority today.

2025: The debate is still live. In late 2025 a citizens' panel proposed rethinking the school day and calendar, including a possible return to a five-day week and shorter summer holidays. https://www.csmonitor.com/World/Europe/2025/1211/france-schools-academic-calendar-class-hours-vacation

Beyond France

Other countries offer partial parallels:

United Kingdom: Facing budget pressure, some schools in England trimmed the school week (often finishing early on Fridays). In 2023 the Department for Education responded with guidance setting a minimum expectation of a 32.5-hour week. This is the closest international echo of the U.S. cost-driven rationale. https://www.gov.uk/government/publications/length-of-the-school-week-minimum-expectation

A caution on Iceland: Iceland's widely publicized "four-day week" refers to a shorter work week, not a school week - a common point of confusion worth avoiding when discussing four-day schools.

The bigger picture: days versus hours

Internationally, how you count school matters as much as how many days it has. France has among the fewest instructional days in the OECD (around 160) yet reaches near-average yearly hours through longer school days - structurally the same trade-off at the heart of the U.S. four-day-week debate.
