Business Day Calendar JP

Closing notices often mean a new image for every holiday. This app puts a calendar on your site that moves forward with the date. In settings you pick your weekly closing days and whether to close for the New Year break (Dec 29 to Jan 3). Japanese national holidays are marked for you. A banner shows the next closure or long weekend with the holiday names. Shops open on holidays can turn on "Open on national holidays" for free. Under 520 px wide the calendar shows one month with arrows; wider, two. Six looks are free. Visitors can switch light and dark view. The display is Japanese or English (Settings or site language). Pro adds one-off closing and opening days, your own colors, background and text size (colors apply in the light or dark view it starts in), and a shipping line such as "Orders placed before 14:00 today ship today." or the next shipping date. You set the cut-off hour; a countdown shows in the last 4 hours (Japan time). Holidays for 2026 and 2027 are built in; after that only weekly closing days and the New Year break count, the banner says so, and no shipping line is shown. No customer data is collected; the app only checks whether your site is on Free or Pro.
