## Tools (as reported by the server, not verified)

- `check\_dates`: For each date, tell whether it is a Japanese national holiday \(with name and kind: 祝日 / 振替休日 / 国民の休日\), a weekend, and a business day. Also returns today in Japan time. With country, the same for that country \(holiday names, status, make-up workdays such as China's 调休\).
- `list\_holidays`: List Japanese national holidays for a year, or between from and to. With no arguments, lists the next 10 holidays from today \(Japan time\). With country, lists that country's public holidays \(and make-up workdays, if any\).
- `business\_days`: Count business days between start and end \(inclusive\), or find the date that is N business days after start \(add=N; negative N goes backward; start itself is not counted\). Business day = weekday that is not a national holiday. Set year\_end\_closed to also skip 12/29-1/3. With country, uses that count
- `find\_long\_weekends`: Find 連休 \(3+ consecutive days off made of weekends and national holidays\), e.g. Golden Week, Silver Week. Give a year, or from \(default today\) to list upcoming ones. With country, the same for that country.
