Public holidays excluded from the 2051 working-day count

These are the 13 public holidays in Japan that land on a weekday in 2051 and therefore remove a working day. Holidays that fall on a weekend are not listed here because they do not change the working-day total.

How working days in Japan are counted in 2051

The 247 working days shown above are the 365 calendar days of 2051, minus the 105 Saturdays and Sundays, minus the 13 public holidays that land on a weekday. Holidays that fall on a Saturday or Sunday are not subtracted, because they do not remove a day anyone would have worked; in 2051 that applies to 3 of Japan's public holidays. At a standard eight-hour day, 247 working days works out to roughly 1,976 working hours across the year, before any annual leave is taken.

What counts as a working day in Japan

Japanese law in article 35 of the Labour Standards Act requires at least one rest day per week or four per four-week period, with no statutory requirement that the rest day be a Sunday. Most office and government work runs Monday to Friday, but retail, manufacturing and small business commonly operate six-day weeks. The civil procedure code article 95 rolls deadlines falling on a Sunday or a kokumin no shukujitsu to the next working day; Saturdays are also excluded by judicial practice though not by statute. Bank settlement follows the Bank of Japan's Zengin system, which observes the full national list of sixteen.

Japan recognises sixteen kokumin no shukujitsu under the National Holidays Act of 1948, the highest count of any major economy. Several modern holidays were introduced under the Happy Monday system enacted in 1998 and extended in 2003, which moved Coming of Age Day, Marine Day, Respect for the Aged Day and Sports Day to a Monday to create three-day weekends. Golden Week clusters four holidays between 29 April and 5 May; Silver Week occasionally creates a similar cluster in September when the autumn equinox falls on a Wednesday. The Emperor's Birthday floats with the reigning emperor: it moved from 23 December to 23 February when Akihito abdicated in 2019.

This matters because the working-day total is not spread evenly. Some months in Japan carry several public holidays while others have none, so the month-by-month table above is the figure to use for payroll runs, billing cycles, SLA windows, and project plans rather than a flat assumption of about 20.6 working days per month. A month with two weekday holidays can have several fewer working days than a clear one, which changes capacity planning and the realistic delivery date for anything scheduled in business days.
