FAQ
This calculator treats Monday through Friday as business days and skips Saturday and Sunday.
No. Enter holidays, PTO, or office closures as weekday adjustments when they apply.
Use it only as a planning check. Legal, court, shipping, payroll, and government deadlines can have specific calendar rules.
Everyday calculators depend on measurement accuracy, rounding, units, local prices, product labels, and whether the inputs describe the same situation.
Round only after checking the formula and units. For materials, money, or time-sensitive tasks, keep an extra buffer when the real-world cost of being short is high.
Different calculators may use different rounding, assumptions, default rates, formulas, or input timing. Compare the visible formula and inputs before relying on the number.
