EVERY MONTH
Writing the same closing days
in four places, every month?
Your website calendar, Instagram, Google Business Profile, and the sign on the door. Every new month means redoing them all, and every unexpected closure means rewriting them again. It is small, endless work that has nothing to do with running your shop.
Set it up once. Then leave it alone.
SOUND FAMILIAR?
Does this happen to you?
- Last month still showingThe month changed, but the calendar on your site didn’t — and a customer pointed it out.
- Holiday Mondays“Closed Mondays, or the next weekday when Monday is a holiday” is hard to show on a calendar.
- No time for a laptopYou need to close today, but there’s no time to open the WordPress dashboard on a computer.
- Re-entering every yearYear-end and summer breaks are typed in again, by hand, every single year.
- It looks datedThe calendar doesn’t match your theme and makes the whole site feel old.

Opening hours are also output as schema.org data, so temporary closures and openings are easier for search engines to read.

FAQ
Frequently asked questions
Do I need to set up the calendar every month?
No. The calendar is calculated from your rules each time it is displayed, so future months are always correct.
Are Japanese public holidays included?
Yes. Holidays are calculated inside the plugin, including substitute holidays and national holidays between two holidays. No external service or yearly update is required.
Can it handle “closed Mondays, or the next weekday when Monday is a holiday”?
Yes. Choose “If a closing day is a holiday, open that day and close the next working day.” Runs of consecutive holidays are handled together.
Can the shop owner update it from a phone?
Yes. The Today screen is built for phones: one tap marks a temporary closure or opening, and Undo reverses a mistake.
Does it match my theme?
The calendar does not depend on your theme. Choose one of three presets, or override the CSS variables in your own stylesheet.
Can I use it as a booking system?
No. Shop Calendar shows opening days. Bookings and event registration are outside its scope.
I use a caching plugin.
If a change does not appear, clear the cache. A cache lifetime of one day or less is recommended.

calendar by hand.
