What is the Business Days Calculator?
A business days calculator counts the plain weekdays (Monday through Friday) between two dates, ignoring weekends — the fastest way to check something like a standard 5-business-day SLA or a T+2 settlement window without a holiday list. It doesn't account for public holidays; for that, and for a choice of weekend pattern, use the working days calculator instead.
How to Calculate
The calculator steps through every date from start to end (inclusive), counting each one as a business day unless it falls on a Saturday or Sunday. It always assumes the standard Saturday+Sunday weekend — if your organisation only treats Sunday as a weekly off, or you need to subtract specific public holidays, the working days calculator supports both.
Formula
Business days = total days − weekend days
