How the Prediction Works

1. Calculate Net Workdays

The tool first calculates the total number of workdays needed:
Workdays = CEILING(Total Estimated Effort Hours / Work Hours per Day)
This ensures any partial day of work counts as a full workday towards the schedule.

2. Apply Buffer

If you provide a buffer percentage, it's added to the net workdays:
Workdays with Buffer = CEILING(Workdays * (1 + Buffer Percentage / 100))

3. Iterate from Start Date

The predictor then starts from your chosen 'Start Date' and counts forward, day by day.

4. Skip Non-Working Days

Each day is checked:

• Is it a weekend? (Based on your 'Workdays per Week' selection: 5-day week skips Sat/Sun; 6-day week skips Sun).
• Is it in your list of specified 'Non-Working Dates'?

If a day is a non-working day, it's skipped, and the tool moves to the next day.

5. Count Workdays

For every day that is identified as a working day, the 'Workdays with Buffer' count is decremented.

6. Predict Deadline

The date on which the 'Workdays with Buffer' count reaches zero is your predicted deadline.

Assumptions

• Work effort is distributed evenly at the specified 'Work Hours per Day'.
• The 'Work Hours per Day' are consistently achieved on each working day.
• Non-working dates provided are accurate.
