Calculation Rules & Exclusions
Project Estimation & Business Day Planning
Accurate sprint estimation and contract deliverables require calculating net working days rather than raw calendar time. By isolating non-working weekend days and factoring statutory holidays, software teams and project managers can commit to realistic ship dates without burnout.
Frequently Asked Questions
How does the working days calculation exclude weekends?
Our algorithm iterates through every calendar date between your start and end range, evaluating the day of the week. Standard weekends (Saturday and Sunday) are excluded, leaving only Monday through Friday business days.
Can I calculate a project deadline by adding working days?
Yes. Under 'Add Business Days to Date' mode, you can enter your project kickoff date and required business days (e.g. 15 working days) to calculate the exact calendar delivery date, automatically skipping intervening weekends and holidays.
Does this tool support 6-day work weeks or Friday-Saturday weekends?
Yes. You can customize the weekend definition to standard Saturday/Sunday (5-day week), Sunday Only (6-day week), or Friday/Saturday (customary in many Middle Eastern regions).
How do custom holidays affect the count?
You can input the number of public or statutory holidays occurring within the timeframe. These are deducted directly from the final business day total.
