FAQ
Can I mix custom weekends with holidays?
Yes. Set both so the calculator excludes weekends and holidays together.
Does Fri Sat weekend always return Sunday?
If Sunday is not excluded and there are no holidays, Sunday becomes the next business day.
How do one-day weekends work?
Only that day is excluded, so the next business day can be closer than with two-day weekends.
Is this guaranteed?
No. It is educational and depends on your inputs and assumptions.
