Frequently asked questions
What’s the difference between a business day and a calendar day?
Calendar days count every day (including weekends). Business days exclude weekends and typically public holidays.
Why does the result change by country?
Because each country has a different public-holiday calendar. Also, some industries treat Saturday as a working day.
Can I use this for legal or banking deadlines?
Use it as a planning aid. Some official deadlines depend on specific definitions (e.g., regional holidays, cut-off times, or jurisdiction-specific rules).
