The Republic of China (ROC) calendar, also known as the Minguo calendar, is a unique system that is used in Taiwan and by some overseas Chinese communities. It was introduced in 1912, marking the beginning of the Republic of China. The ROC calendar starts from the year 1912, known as Year 1 of the Republic. It is based on the Gregorian calendar but uses different era names to indicate the years. The era names are derived from significant events or political changes in the country's history. For example, the current era is called "Minguo," meaning "Republic" in Chinese. Additionally, the ROC calendar follows a solar system, with each year consisting of 365 or 366 days, depending on leap years. It also retains elements of the traditional Chinese calendar, incorporating the lunar months and zodiac signs for determining holidays and auspicious occasions. While the ROC calendar is not widely used internationally, it holds cultural significance in Taiwan and serves as a reminder of the country's history and political evolution.

The current year is 112. The ROC calandar is used only in some official cases in Taiwan. Personally I have not worked out exactly when it is and isn't used, but I see it most often in bank statements and government documents and press releases.

Resolves YES if the Taiwanese government announces it is abandoning the calendar for all official uses. Resolves NA if the ROC (Taiwan) ceases to exist before 2040.
