Of your 10 annual PTO days, which ones turn into the most rest? This page ranks them by one number — efficiency. Spend PTO randomly and you'll add a day here and there. Spend it from the top of this list and you'll build the year's biggest blocks.
Looking forward, the next year with at least as many efficiency 1.5+ patterns is 1 years out (2027 · 16 patterns). In high-supply years like that one, the discipline shifts: don't take every top-ranked day, allocate them to the 4:4:2 split.
Assumes Japan's current Holiday Law (Act on National Holidays, 1948) and the Happy Monday / substitute-holiday rules remain in force; special acts and revisions can shift this.

* Efficiency = (PTO-extended block length − natural rest length) ÷ PTO days used. Efficiency 2.0 means "one PTO day, two extra rest days."

How to read this list

  • Efficiency 2.0+One PTO day buys two extra rest days. The strongest PTO investments of the year — fill the calendar from these first.
  • Efficiency 1.5–2.0Solid but not heroic. Multi-PTO patterns (Golden Week or September extensions) tend to land here.
  • Why some dates appear in multiple rowsRows represent different choices for the same holiday window. Decide whether you want to spend 1, 2, or more days to get the block length you need.
  • Relationship to the 10-day allotmentThe recommended split is 4 days for big blocks, 4 for small recoveries, 2 reserve (4:4:2). Full strategy breakdown on the main year page.

Practical tips for spending PTO

  • Request 1–2 months earlyHigh-efficiency dates are popular. Golden Week and September especially. Share the plan early so scheduling stays smooth.
  • Keep the return week lightThe longer the block, the heavier the catch-up afterwards. Don't schedule new initiatives the week you return.
  • Don't empty the reserve bucketAlways hold about 2 days for sick days or family emergencies. Don't spend your entire annual budget on long weekends.
