Business Days Calculator
Count working days between two dates or add and subtract business days with custom weekends and holidays.
Calculate business days
Method
Each calendar date is checked against the selected weekend pattern and your holiday list. Adding days does not count the starting date as day one.
Holiday source
Holiday schedules vary by state and institution. Use the National Portal of India holiday calendar or the relevant employer, bank, court, or exchange calendar.
Limitations
The result is an arithmetic schedule, not a legal deadline calculation. Cut-off times, emergency closures, local holidays, settlement calendars, and jurisdiction-specific rules are not inferred.

Frequently asked questions
What counts as a business day?
A business day is any date that is not one of the weekend days you select and is not in your optional holiday list.
Can I include the start and end dates?
Yes. In between-dates mode, select the inclusive option to count both boundary dates when they qualify as business days.
Are Indian holidays added automatically?
No. Holidays vary by state, institution, and year, so paste the relevant dates from an authoritative calendar.
