Count Monday through Friday between two dates. You can leave out dates that should not count.
1 January 2024 through 5 January 2024 is five business days.
6 January 2024 through 7 January 2024 is Saturday and Sunday, so the business-day count is 0.
Each date from the start through the end, when the end is included, is a weekday or a weekend day. Monday through Friday count as business days unless you excluded that date. Saturday and Sunday count as weekend days. If the end date is earlier, the page counts the span between the two dates.
There is no country holiday calendar. A holiday counts as a business day unless you exclude it.

Take a percent off a price and see the amount saved and what you pay. Type plain numbers. A currency symbol is invalid, and a discount above 100% is rejected.
