The modern five-day workweek forms the operational standard for global trade, banking, and civil government. Labor laws set the standard business week. It provides five operating days from Monday through Friday. Financial markets and banks follow this five-day cycle. Calculating business days separately from calendar days is essential. It ensures contracts match active banking hours.

How does adding 5 business days differ from adding 7 calendar days?

How does the calculator handle starting on a Saturday or Sunday?
When you pick a weekend start date, counting begins on the next workday. Starting on Saturday and adding one workday starts counting Monday. The engine delivers Tuesday as the final date. This design matches standard bank rules. It eliminates weekend confusion for contract deadlines across teams.
What does T+1 and T+2 settlement mean in financial markets?
