About the Business Days Calculator
What is the Business Days Calculator?
This business days calculator counts working days between two dates, leaving out weekly offs and any holidays you list.
It supports Saturday-Sunday, Sunday-only and Indian bank weekends (2nd and 4th Saturdays).
How to use the Business Days Calculator
- Start Date (sample: 22 Oct 2026)
- End Date (sample: 21 Nov 2026)
- Weekly Off (sample: Saturday and Sunday)
- Holidays to Exclude (optional)
- Press Count Business Days (results also refresh as you type). The result card shows the Business Days, along with Calendar days (both dates included), Weekly off days, Holidays on working days and Working hours at 8 h/day.
Formula used
Business days = Calendar days − Weekly offs − Holidays on working days
Both the start and end dates are counted.
