:mrdocs:

Load, into the specified `result`, the date corresponding to the specified `n`th business day of the specified `month` and the specified `year` based on the specified `calendar`. A positive value of `n` indicates that counting the number of business days begins from the first calendar date of the month (inclusive), and a negative value of `n` indicates that counting the number of business days begins from the last calendar date of the month (inclusive). If there are fewer than `abs(n)` business days in the month according to the `calendar`, the business day furthest from the first date of the month is chosen if `n > 0`, and the business day furthest from the last date of the month is chosen if `n < 0`. Return 0 on success, and a non‐zero value, without modifying `*result`, if the entire month specified by `year` and `month` is not within the valid range of the `calendar` or there are no business days in the month specified by `year` and `month`. The behavior is undefined unless `n != 0`, `1 <= year <= 9999`, and `1 <= month <= 12`.
