Frequently Asked Questions
What is the Project Timeline Calculator?
This tool helps project managers and planners estimate the start date, end date, and overall duration of a project based on the number of tasks, average task duration, and specific working days.
Does the calculator include weekends in the timeline?
By default, the calculator typically excludes weekends (Saturday and Sunday) from the calculation to reflect standard business working hours, though this can often be toggled in the settings.
How is the 'Buffer' percentage applied?
The buffer percentage adds extra time to your estimated total duration to account for unforeseen delays, risks, or resource unavailability. For example, a 20% buffer on a 10-day schedule adds 2 extra days.
Can I calculate backwards from a deadline?
Yes, if you select the 'Calculate Backwards' or 'End Date' mode, you can input your desired project completion date, and the tool will determine the latest possible start date to meet that deadline.
How are public holidays handled?
You can usually specify a list of non-working days or public holidays in the advanced settings. The calculator will skip these dates when counting working days for the project.
Why is the calculated duration longer than the sum of task days?
This likely occurs because the calculator accounts for non-working days (weekends and holidays) and may include the buffer percentage. It reflects 'calendar days' rather than just 'man-hours'.
