Tools of Business Days & Workday Calc
	Description		Read-only	Idempotent	Open world
`add_business_days`Use this when the user asks what date is a number of working days, business days or workdays after or before a date, including an SLA due date or turnaround, for example "what date is 37 business days after 11 August in England?" or "5 working days before 20 December in the US". Pass the country code, the start date as YYYY-MM-DD, the number of days (negative for earlier) and a region when the user names one. The start date is day 0 and is not counted. Returns the resulting date and weekday, the holidays skipped, and the conventions used. At most 1000 business days. For a trade's settlement date (T+1, T+2) pass calendars, such as ["NYSE", "FED"], ["LSE"] or ["JPX"]. Do not use it for legal deadlines that follow their own court or contract rules, or for calendar-day offsets.

`count_business_days`Use this when the user asks how many working days, business days, workdays, office days or PTO days there are between two dates, or for a statutory holiday count, for example "how many working days between 14 July and 18 August in Germany?" or "how many working days are left in December in Ontario?". Pass the country code, the start and end dates as YYYY-MM-DD, and a region when the user names a state or province. Both dates count by default (see includeStartDate and includeEndDate). Weekends are Saturday and Sunday unless weekendDays is set. Returns the business, calendar and weekend day counts, the holidays on working days, those only some regions keep, and the conventions used. For exchange trading days pass calendars, such as ["NYSE"], ["LSE"], ["JPX"] or ["TARGET2"]. Do not use it for hours, time zones, or date differences that do not exclude weekends and holidays.

`list_holidays`Use this when the user asks which public holidays, bank holidays, statutory holidays or school breaks a country, state or province has in a year, for example "is Monday a bank holiday in Bavaria?", "public holidays in Vietnam in 2027" or "school holidays in Bavaria".

Public holidays come back with the date, weekday, English and local name, whether they apply nationwide or in listed regions, and whether they are a day off.
