Create and print a simple monthly calendar entirely in your browser. Pick a year and month and the calendar is drawn instantly, ready to print or write on. Sundays are shown in red, Saturdays in blue, and Japanese public holidays (including substitute and citizens' holidays) are shaded and labelled automatically, so it works as a blank planner you can fill in by hand. You can start the week on Sunday or Monday, and today's date is outlined for quick reference. Add a heading such as "June plans" in the title field to print it with a caption. When it looks right, download it as a PNG or print it directly — it is sized to fit a single A4 landscape sheet, so it is convenient for convenience-store printing too. No templates to browse and no sign-up: change the year or month and the next month or next year is ready at once. Rendering and holiday calculation all happen in your browser; nothing you enter is uploaded or stored.

  2. Choose the week start (Sunday or Monday) and toggle holidays and holiday names as needed.
  3. Click "Download PNG" to save it, or "Print" to print directly (sized to fit one A4 landscape sheet).

FAQ

Are Japanese public holidays included?

Yes. Holidays are computed in your browser from Japanese holiday law, including substitute holidays and citizens' holidays; matching days are shaded and labelled (reliable roughly 2000–2099). Company-specific closures are not included.

Can I use it as a blank planner?

Yes. The cells contain only the date, with room left below, so you can print it and write your schedule in by hand.

Can the week start on Monday?

Yes. You can start the week on Sunday or Monday; the weekday colour-coding (red for Sunday, blue for Saturday) adjusts automatically.

Is anything I enter stored?

No. Rendering and holiday calculation all run in your browser; the year, month and title you choose are never sent to any server or stored.
