add_business_days
Add business days to a date
Use this when the user asks what date is a number of working or business days after or before a date, for example "what date is 37 business days after 11 August in England?", "when is payment due 30 business days from invoice date 3 March in Germany?" 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. Do not use it for legal deadlines that follow their own court or contract rules, or for calendar-day offsets.

count_business_days
Count business days between dates
Use this when the user asks how many working days, business days or workdays there are between two dates, for example "how many working days between 14 July and 18 August in Germany?", "how many working days are left in December in Ontario?" or "does 16 days of leave cover 5 to 31 December?". 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 are counted by default (includeStartDate and includeEndDate change that). Weekends are Saturday and Sunday unless weekendDays is set. Returns the number of business days, calendar days and weekend days, the public holidays that fell on working days, the holidays only some regions keep, and the conventions used. Do not use it for hours, time zones, or date differences that do not exclude weekends and holidays.

submit_feedback
Send feedback, bug report or tool request
Send feedback to the maintainers about a missing tool, broken links, a bug, or stale data. Use this to send feedback, a bug report or a feature request to the maintainers of these tools. Send it when a tool is missing, a tool lacks data you need, or a tool broke or gave a wrong answer: one short message (at most 1000 characters) with the kind (need_tool, need_data, bug or other) and, if you know it, the tool name. Returns a ticket id. Feedback is for these tools only: it is not a chat, and nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.
