Daily load

4.0 focus hours per available workday are needed to fit the estimate.

Blackouts

No custom blackout dates were removed from capacity.

Notes

Keep scope changes out of the final week unless they replace lower-priority work.

Method

The planner counts local Gregorian dates and capacity assumptions

The calendar orders the selected start and deadline, counts inclusive calendar days, removes Saturdays, Sundays and listed blackout dates from workday capacity, then spreads default delivery phases across the available date range.

Capacity is editable

Estimated hours, focus hours per workday and workdays per week are planning assumptions. The buffer tells you whether the current plan fits those assumptions.

Print path

The print button opens browser print. The print stylesheet keeps the project header, summary, phase plan, weekly calendar, notes, assumptions and limits.

Limits

This is delivery planning math, not contract, procurement, employment or legal advice. Confirm externally promised dates before publishing.

Source Notes

Civil-date arithmetic with visible assumptions

CalculationTime uses browser Date objects for local Gregorian date stepping and ISO-style YYYY-MM-DD values for form input. No official holiday, contract, staffing or resource-management dataset is bundled into this page.
