- The fullest month is December with 23 working days; the lightest is February with 18.
- Counts use nationwide holidays only — regional ones (a state day in the US, a cantonal day in Switzerland) reduce the total further where they apply.
- Weekends are Saturday and Sunday. Half-day customs — a Christmas Eve afternoon, a Bayram eve — are not subtracted.
Which holidays are subtracted
The 15 nationwide holidays falling on weekdays come from the same dataset as the Japan public holidays 2025 page, which lists each one with the weekday it lands on — and how Japan's holiday system works:
- Japan runs a substitute-holiday rule — furikae kyūjitsu: when a national holiday falls on a Sunday, the next working day becomes a holiday. The observed dates are what this page shows.
- The Happy Monday System moved several holidays to Mondays on purpose — Coming of Age Day, Marine Day, Respect for the Aged Day and Sports Day — to manufacture three-day weekends.
- Golden Week stacks four holidays between 29 April and 5 May; with the substitution rule it regularly produces the country’s longest break, and any weekday gap in it becomes a de facto bridge day.
