NACOSE Business Day Calendar

NACOSE Business Day Calendar shows a monthly calendar of the days your business is open and closed.

• Japanese public holidays are built in. Fixed holidays, “Happy Monday” holidays, the equinoxes, substitute holidays and Citizens’ Holidays are calculated by the plugin for 2000-2099. No external service or API is used.
• Regular closing days by rule. Choose weekdays (every Sunday) and “Nth weekday” days (2nd Monday, last Friday) from a simple table. Decide whether public holidays are closing days.
• Rules that change over time. If your closing days change from a certain date, add a new rule with its start date. Past months keep showing the old rule.
• Temporary closings and special openings. Register a whole period at once (summer break, inventory days), optionally repeating every year (New Year break). A special opening overrides regular closing days and public holidays.
• Public holiday adjustments. Remove a holiday or add your own on the settings page, for example after a change of the law, without touching code.
• Business hours. Set default hours and different hours for single weekdays, and show them together with your regular closing days.
• Easy to show. Add [business_day_calendar] to any page, post or widget. Colors and legend text can be changed.
• Accessible. Closed days also carry text for screen readers, not only color.

Shortcode

• [business_day_calendar] – this month, with previous / next month links
• [business_day_calendar months="3"] – several months
• [business_day_calendar month="2027-01"] – a fixed month
• [business_day_calendar nav="no" legend="no"] – hide the month links and the legend

• [business_day_today] – a line such as “Today (10/21 Wed) is a business day.” It stays correct on pages kept by a page cache, because a small script picks today’s entry in the site time zone.

• [business_hours] – business hours and regular closing days, for example “Mon-Fri: 9:30 – 18:30” and “Sunday, 2nd Monday, Public holidays”. Use closed="no" to hide the closing days.

For developers

The filter bdcjp_holidays lets you add, remove or rename public holidays for a year (for example after a change of the law). It receives an array of 'Y-m-d' => 'name' and the year.
