Name the starting event
A duration is ambiguous until the exact event that starts the clock is defined.
Business Day Deadline Calculator
Calculate a working deadline from a start date, business-day duration, review buffer, weekends, and known excluded dates.
Use the output as a decision draft.
Separate work and review
Production time and client decision time should be visible rather than blended into one estimate.
Confirm local calendars
Weekend and excluded-date assumptions vary across teams, clients, suppliers, and jurisdictions.
Recalculate after change
A missed input or changed dependency should produce a new visible commitment, not a hidden compressed schedule.
What to know before using it.
Are public holidays included automatically?
No. Add known non-working dates explicitly. Holiday calendars vary by location, organization, client, and supplier.
Does the first day count?
The calculator begins counting working days after the selected start date. Use the start date as the event that releases work to begin.
What are buffer days?
They are additional working days reserved for review or uncertainty. Keep them visible so they are not mistaken for production effort.
Turn the draft into live work.
Continue in Stelaah when the result needs owners, client context, decisions, files, dates, and progress.
