Japan Public Holidays

By omikuji · All Omikuji servers

Japanese national holidays from the Cabinet Office data: check dates (holiday / substitute holiday / business day), count business days, find the date N business days later, and list long weekends. Does not guess unannounced years. 内閣府のデータで、日本の祝日・振替休日・営業日・連休を答えます。N 営業日後の計算や、ゴールデンウィークの日数も。未発表の年は推測しません。
