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. |
