fixed holiday profile: Constitution Memorial Day is one piece of Japan's Golden Week cluster, so its importance comes from both civic meaning and the way it joins a high-travel holiday period.
Local specificity checkpoint
Local specificity comes from the selected country calendar row, local name, observance type, timezone record, nearby holidays, and observed cross-country date spread.
Dossier checkpoint
Constitution Memorial Day is the middle pillar of Golden Week's trio of consecutive holidays: Shōwa Day (29 April, formerly Hirohito's birthday) → Constitution Memorial Day (3 May) → Greenery Day (4 May, formerly the original location of the post-Hirohito environmental holiday before it was displaced) → Children's Day (5 May). It contrasts with the imperially-tied dates around it — Shōwa Day and the Emperor's Birthday — as the only Golden Week holiday rooted in republican-democratic constitutional law rather than the Imperial House. Source citations are rendered in the holiday-specific dossier.
Reference stack
This block separates the local Japan holiday answer from two common sources of programmatic-calendar confusion: countries that use the same holiday name on different dates, and future rows that are projected from a rule rather than directly tracked.
Cross-border date spread
Constitution Memorial Day is currently anchored to Japan in the observed-country dataset, so cross-border date drift is not a major concern on this page.
Projection reliability
Constitution Memorial Day has a projectable fixed-date pattern, but projected rows are explicitly labeled and should not be treated as official statutory notices. Source posture: 3 curated source citations attached.

Country calendar role
Constitution Memorial Day is recorded in Japan as a public holiday with nationwide scope.
Reference fields include Constitution Memorial Day's country, date behavior, timezone context, related holidays, and observed-country coverage.
The date commemorates Japan's post-war constitution and sits inside a broader spring sequence that reshapes domestic movement, leisure, and business closures each year.
That combination of constitutional symbolism and Golden Week timing makes it more consequential than a standard one-day civic observance.
Constitution Memorial Day is marked as a nationwide observance in the current Japan holiday data.
Constitution Memorial Day is scheduled on May 3 each year. In the tracked 2025-2027 data window, it stays on May 3 and only the weekday changes.
Because Constitution Memorial Day stays on the same calendar date, the only year-over-year planning shift is the day of the week — that controls long-weekend math, school-closure timing, and how the holiday lands in payroll cycles.
The current static build keeps the tracked 2025-2027 date window online for curated holiday detail pages.
| Year | Date | Day |
|---|---|---|
| 2025 | May 3, 2025 | Saturday |
| 2026 | May 3, 2026 | Sunday |
| 2027 | May 3, 2027 | Monday |
The first rows are taken from the tracked catalog window (2025-2027); rows after the catalog cut-off are projected forward because Constitution Memorial Day has a fixed-date rule. Easter-cycle, lunar, and country-specific custom-rule holidays are never projected — those rows simply stop at the catalog edge.
| Year | Date | Weekday | Source |
|---|---|---|---|
| 2027 | May 3, 2027 | Monday | Catalog |
| 2028 | May 3, 2028 | Wednesday | Projected (fixed rule) |
| 2029 | May 3, 2029 | Thursday | Projected (fixed rule) |
| 2030 | May 3, 2030 | Friday | Projected (fixed rule) |
| 2031 | May 3, 2031 | Saturday | Projected (fixed rule) |
Projected rows assume the fixed-date rule continues to repeat the same calendar date; weekend-substitution and other statutory adjustments may shift the actual local observance day.

Differentiates from neighbors
Constitution Memorial Day is the middle pillar of Golden Week's trio of consecutive holidays: Shōwa Day (29 April, formerly Hirohito's birthday) → Constitution Memorial Day (3 May) → Greenery Day (4 May, formerly the original location of the post-Hirohito environmental holiday before it was displaced) → Children's Day (5 May). It contrasts with the imperially-tied dates around it — Shōwa Day and the Emperor's Birthday — as the only Golden Week holiday rooted in republican-democratic constitutional law rather than the Imperial House.
Religious / civic / cultural context
Kenpō Kinenbi (憲法記念日) commemorates the entry into force of the 1947 Constitution of Japan, drafted under the Allied Occupation by SCAP staff in consultation with Japanese legal scholars and enacted by the Imperial Diet. The constitution's three pillars — popular sovereignty, fundamental human rights, and pacifism (Article 9 renouncing war and the maintenance of war potential) — make the day a focal point of post-war Japanese civic identity. It carries no religious component; in contemporary politics it has become the principal annual flashpoint for the debate over revising Article 9.
Date rule
Fixed on 3 May each year under Article 2 of the Act on National Holidays (Law No. 178 of 1948), commemorating the date in 1947 on which the post-war Constitution of Japan took legal effect (six months after its 3 November 1946 promulgation). If 3 May falls on a Sunday, the substitute-holiday rule (furikae kyūjitsu) shifts the day off to the next non-holiday weekday, typically 6 May.
Planning impact
Constitution Memorial Day anchors the back half of Golden Week (29 April Shōwa Day → 3 May Kenpō Kinenbi → 4 May Greenery Day → 5 May Children's Day), the year's longest contiguous Japanese shutdown — typically 7-10 days when weekends and corporate paid leave are stacked in. Treat the full Golden Week corridor as Tokyo-dark for trading, deployments, and approvals; domestic travel demand peaks (Shinkansen reservation books open one month prior and fill within hours). EU/US firms should expect a hard reply delay from Japanese counterparties from late April through 6 May.
Observance mode by jurisdiction
Country-specific behavior
Only countries whose pattern departs from the headline observance rule are listed.
Japan
Sole observing country; fixed 3 May. When the date falls on a Sunday, the make-up day shifts forward past 4 May (Greenery Day) and 5 May (Children's Day) to land on 6 May — a consequence of the Act's clause that bridges consecutive holidays.
Sources
As a secular civic holiday sitting in the Japan calendar, Constitution Memorial Day matters for planning because office, bank, and school closures stack on the same day. The next tracked occurrence is May 3, 2027 (Monday), which controls long-weekend math for that year.
Constitution Memorial Day also appears in other country calendars such as Japan. Recorded next dates include Japan on May 3, 2027 — slight differences across borders are common because each country can apply weekend-substitution or regional-only rules to the same nominal holiday.
Japan plans this holiday primarily around Asia/Tokyo. Because Constitution Memorial Day stays on the same calendar date, the only year-over-year planning shift is the day of the week — that controls long-weekend math, school-closure timing, and how the holiday lands in payroll cycles. Teams often line Constitution Memorial Day up with New Year's Day, Children's Day, and Greenery Day when blocking off the broader holiday window.
