Japan holidays and business days
Use "JP" for the Japan country-level calendar. The following coverage describes the pinned release 2026-09-15-holidays-0.104-t0-repair-5.
Weekend rule
Saturday–Sunday, using the Monday-to-Sunday mask 0000011 throughout 2000–2035 in this release. The optional weekend argument overrides the default; extra closures and public holidays still take precedence.
Coverage is statutory weekend only: this code has no source working-weekend data. We do not infer make-up working days or employer-specific schedules.
Subdivision support
No subdivisions are exposed by the pinned source. The national calendar includes the source’s observed and substitute holiday dates.
0 subdivision entries. =SUBDIVISIONS("JP") lists the supported suffixes and names on either plan. Using a regional calendar requires Pro.
Complete years and estimated dates
The national calendar has complete years 2000–2035 in the pinned audit. Each subdivision has its own completeness flags; do not infer regional completeness from this national range.
First estimated year: none labelled in 2000–2035 for this national calendar or its listed subdivisions. No label is not proof of confirmation; completeness is checked independently.
Estimated dates can move by a day when authorities confirm them. Holiday names preserve the source’s " (estimated)" suffix where supplied; some source names suppress that label.

Free and Pro
Free: every formula for the current calendar year and the next one, in the spreadsheet’s timezone; country-level only, no subdivisions and no custom extra ranges. In 2026, that window is 2026–2027.
Pro: $29/year or $4/month; holiday lists: 2000–2035, subject to source coverage; business-day formulas: years with published calendars. Includes subdivisions, custom extra ranges, and priority data corrections. Compare plans and owner-based access.
Calendar coverage and estimated dates
Estimated dates can move by a day when authorities confirm them. HOLIDAYS and HOLIDAYNAME preserve the source’s exact " (estimated)" suffix where supplied. An absent label does not prove that a date is confirmed.
For codes without working-weekend data, coverage is statutory weekend only: public holidays and the configured weekend rule, with no inferred make-up working days. Business-day formulas require a complete calendar for every year touched; Pro does not unlock unpublished calendars. Read the data coverage guide.
