Your sprint plan assumes 10 days × N people. Your calendar disagrees.
Name where your team sits and the window you’re planning. This subtracts the public holidays each country actually observes and the time off you’ve booked — then shows the working days and person-days that are left, and whether what you’ve committed fits inside them.

496 person-days, not 528. 66 working days on a Mon–Fri week × 8 people is where the 528 comes from.

Which days, and for whom
- Mon 11 Oct4 of 8 offUnited States · Columbus Day
- Mon 1 Nov4 of 8 offPoland · Wszystkich Świętych
- Thu 11 Nov8 of 8 offPoland · Narodowe Święto NiepodległościUnited States · Veterans Day
- Thu 25 Nov4 of 8 offUnited States · Thanksgiving Day
- Fri 24 Dec8 of 8 offPoland · Wigilia Bożego NarodzeniaUnited States · Christmas Day (observed)
- Fri 31 Dec4 of 8 offUnited States · New Year's Day (observed)
4 of these dates take out part of the team only — the window carries days where some of the team is off and the rest is working.
Only holidays landing on a working day are listed. Where a country moves one that falls on a weekend onto a weekday, the moved date is what appears, marked observed; where it does not, the holiday costs the window nothing and is left out.
What the holiday dates exclude
Coverage is national. Regional, state, municipal and religious holidays are not in these numbers, and neither are company shutdown days or collective-agreement days off unless the note below says otherwise. Every date is computed from a rule rather than fetched, so it holds for any year — but a rule cannot know about a one-off national holiday declared for a royal jubilee or a funeral.
- United States
- Federal holidays only; state holidays are excluded. No private employer is required to close on any of these, so a US team may well work through some of them.
- Poland
- Poland has no regional public holidays, so this is the full national set. Easter and Pentecost Sunday are omitted; they never fall on a working day. Christmas Eve counts from 2025, when it became a public holiday. A holiday falling on a Saturday earns a compensating day off under working-time law, but the employer schedules it, so it has no fixed date and is not modelled here.
Step 2 — the commitment check
Against 496 available person-days rather than the 528 the plan assumed. Turning those into points needs a points-per-day pace, and the only honest source for one is your own last few sprints — without them, this shows the person-days and stops there.
What this can and cannot see
Holiday dates are computed from rules rather than fetched from a list, so they hold for any year — but coverage is national only, and each country’s exclusions are spelled out beside the result. The commitment check is arithmetic on the numbers you enter plus the sprint totals you give us. No cross-team benchmark stands behind it, because none exists: nobody can tell you how often commitments like yours land elsewhere, and a number that claimed to would be invented.
