ganak.appBusiness Days Calculator
Add business days, excluding weekends and holidays.
This calculator lets you start from a specific date and move forward by a set number of business days, automatically skipping weekends and optional holidays. Instead of counting on a calendar and worrying if you've accidentally included a Saturday or Sunday, the tool does the work for you.
You choose the starting date, enter how many business days you want to add, and select the weekend pattern that matches your region or company (for example, Saturday–Sunday or Friday–Saturday). The calculator then jumps ahead, skipping those non-working days and any holidays you've configured, and shows the exact resulting date.
It's ideal whenever you need a realistic finish date based on actual working time, not just calendar days.
- Project Deadlines: Start from a kickoff date and add the number of working days to estimate a realistic delivery date.
- Task Planning: Plan how many business days it will take to complete tasks, then quickly see when you'll finish.
- Onboarding & Training: Add business days to hire or start dates to define training end dates that only count active working days.
- Service & Support Commitments: When SLAs are defined in business days, add the promised business days to the ticket open date to find the due date.
- Compliance & Regulatory Timelines: Calculate due dates or response windows based on business days instead of full calendar days.
Short-Term Task Planning
A task starts on Monday, 3 February 2033. Adding 5 business days with a Saturday–Sunday weekend pattern lands you on the following Monday, skipping the weekend automatically.
Regional Weekend Pattern
In regions where Friday–Saturday is the weekend, adding 10 business days from a Monday date will skip Fridays and Saturdays, but include Sundays as working days.
Longer Project Timeline
If a small project begins on April 1, 2025 and you expect it to take 40 business days, the calculator gives you the exact completion date after excluding weekends and holidays.
Avoiding Manual Errors
Instead of counting squares in a calendar and miscounting weekends, you enter "20 business days" from a given start date and let the tool return the correct end date in one step.
