🇮🇳Compare working days across countries, then plan team capacity for distributed Agile and SAFe planning increments.
Distributed team capacity planner
Use this for a SAFe Planning Interval (PI) or another fixed planning increment that crosses geographic boundaries. It shows how weekends and holidays affect available team capacity in each location and in the shared delivery window.
Planning note: Person-days are a capacity input, not a promise. Keep story-point velocity as a separate, empirically measured team metric.
Worked example: a U.S.–India planning increment
For October 5–December 18, 2026, with eight people in each location, 100% availability, and a 70% focus factor:
- United States: 52 working days
- India: 54 working days
- Shared delivery window: 51 days
- Combined adjusted capacity: 593.6 person-days
The difference is caused by country calendars—not by a different elapsed date range. In a real PI, subtract known leave, training, ceremonies, support rotations, and other planned work before comparing the result with historical velocity.
Compare business days across any two countries
International deadlines are rarely just calendar math. A U.S. project manager, an India delivery team, and an external customer may count the same deadline differently because weekends and public holidays do not line up. Select any two countries to create a transparent planning estimate using the same dates and assumptions.
What the results mean
- Total days counts the elapsed calendar difference between the selected date and the reference date. Weekends and holidays remain included.
- Working days removes each country’s weekend. For supported countries, it also removes common national and public holidays.
- Compare countries shows each country’s result separately. A date can be a working day in one country and a holiday in the other.
Example planning question
Suppose a customer asks when an invoice or project handoff will be reached after a given date. Start with Days till, enter the target date, choose the reference date if you do not want to use today, and select Working days. Compare the two results before promising a delivery date. If the work must proceed in both countries, review the country with the smaller count and check the holidays manually.
Coverage and limitations
Holiday-aware planning currently covers the United States, India, United Kingdom, Canada, Australia, Germany, France, Japan, and Singapore using common national or widely observed public holidays. Country calendars can vary by state, province, territory, religion, employer, and annual government announcement. Other countries can still be selected for weekday-only estimates. Always confirm a consequential deadline against the relevant official or employer calendar.
Using this for SAFe and distributed Agile planning
A planning increment’s calendar is one input to capacity. Use the country comparison to identify holiday and weekend differences, then adjust for team availability, planned leave, ceremonies, support work, and a team-specific focus factor. Do not multiply working days directly into story points; use the optional ratio only when it comes from the team’s own historical data.
Planning with AI-augmented full-stack teams
AI tools can reduce handoffs and help a full-stack engineer complete more work independently, but they do not eliminate calendar constraints. Teams still need coverage for production support, reviews, customer decisions, security approvals, leave, and regional holidays. Use this planner to model those real availability constraints, then apply your team’s observed delivery data rather than assuming that more working days automatically produce more story points.
Frequently asked questions
Does a working day mean my company is open?
No. The result is a planning estimate based on weekends and the selected holiday rules. Companies may close for floating holidays, regional observances, shutdowns, or internal events that are not included here.
Why are the two country results different?
Each country has its own weekend and holiday schedule. The difference is useful when coordinating a handoff, support window, invoice deadline, payroll date, or service-level target across both locations.
Can I compare countries other than the United States and India?
Yes. The selector includes countries worldwide. The United Kingdom, Canada, Australia, Germany, France, Japan, and Singapore now have common holiday calendars in addition to the U.S. and India. Other selections use weekdays only and identify that limitation in the result.
Are the dates inclusive?
The calculator reports the elapsed date difference between the start and end points. For working-day planning, confirm whether your organization treats the start date, deadline date, or both as billable or available workdays.
Can I use this for payroll, legal, or contract deadlines?
Use it as a starting point, not as the sole source for a legal, payroll, tax, compliance, or contract decision. Verify the governing calendar and the exact counting convention with the responsible organization.
