The Republic of China accepted the Gregorian calendar from January 1st in the year 1912. Each year has 12 regular lunar months.

According to the people in those days the calendar was a sacred and royal property. The astronomers predicted the major events like an eclipse and if some unforeseen natural calamity occurred then the calendar went for a total make over. The calendar in those days was inscribed on oracle bones. Like the western Callipic cycle and Metonic cycle the Chinese calendar too was calculated under various schemes. After the winter solstice the new moon would mark the beginning of a new year. The current 60 year cycle has started in the year 1984.
