- Enter Weekend pattern, Holiday dates, and Search window (days) for the recurrence cutoff.
- Generate the Vacation Day Optimizer output and review its first Search window (days) cycle.

Calculation
Method used

Visual audit
Reading the generated calendar
The Vacation Day Optimizer calendar generates entries from First day away, Leave days available, Weekend pattern, Holiday dates, and Search window (days). Review Search window (days) across full cycles, weekends, and month boundaries.
Worked scenario
Example calculation
Check the Vacation Day Optimizer example anchor with First day away and Leave days available, then review the Search window (days) boundary direction.
Interpretation
Reviewing the generated schedule
The result is a candidate continuous break, not a guarantee that those dates are optimal across the full organization calendar.
Review Search window (days) on each Vacation Day Optimizer date; check that Search window (days) with the recurrence basis and cutoff.
Pair this Vacation Day Optimizer result with the Rotating Shift Schedule Generator when you also need to build a repeating work calendar from days on, days off, shift length, and team count.
Practical use
Recommended workflow
Enter the official holiday calendar, compare several starting dates, and submit the preferred block only after checking team coverage.
Boundaries
Important edge cases and limitations
Blackout periods, half-days, variable schedules, approval priority, and holidays not entered by the user are excluded.
Revise Search window (days) through the Vacation Day Optimizer inputs; generate the full cutoff set instead of editing one date.

Questions
Frequently asked questions
Why must holidays be entered manually?
Holiday observance differs by employer, country, region, and year. Manual dates prevent the calculator from assuming the wrong calendar.
What event should trigger another vacation day optimizer calculation?
Reconsider the Vacation Day Optimizer when Search window (days) no longer matches the source used for First day away. A new calculation keeps the cases separate.
Can an error in First day away shift the vacation day optimizer output?
First day away anchors the Vacation Day Optimizer sequence, while Search window (days) controls its recurrence or review horizon. Check the anchor before comparing individual dates.
Which vacation day optimizer output is most affected by
Change only Search window (days) and regenerate the Vacation Day Optimizer. In the Vacation Day Optimizer, the first changed occurrence shows where the revised Search window (days) cycle or boundary begins to matter.
