Business-day calculations underpin everything from invoice due dates to product delivery commitments. A small error compounds — a missed deadline today is a missed quarter tomorrow.
Define your working week
Most teams default to Monday–Friday, but support, retail, and healthcare teams often work seven days. Pick one and document it for the team — every business-day calculator should match the same definition.
Add the right holidays
Public holidays differ by country and region. Use the Business Days Calculator's custom holiday list to add only the dates that actually pause your work — not every holiday on the calendar.
Distinguish elapsed vs business time
An SLA of '24 hours' usually means business hours, not 24 elapsed hours. Use the SLA Timer to track response and resolution under business-hour rules so you avoid breaching at midnight on a Saturday.
