The Gregorian Calendar: 1582, Pope Gregory XIII

September means "seventh" but is the ninth month. That's because, according to infoplease.com, the Julian calendar (Julius Caesar, 45 BC) was updated about 1582 AD under Pope Gregory XIII. The calendar had to be lengthened. The seventh month was bumped to ninth position.

What other months are anomalies? Octo means "eighth" but is the 10th month. Deca, as in December, might be the tenth but is the 12th month.

new words:
septuagenarian
anomaly
