Zen of Python violated by Python

[Skaperen]

the big irony ... years numbers are 1-based. yet, a few years ago, around the turn of the century, so many people actually thought years were 0-based and said 2000 was the new century. but 2001 was. there never was a year 0. the 1st century began with year 1 and ended at the end of year 100. year 101 was the start of the 2nd century which ended at the end of year 200. year 1901 was the start of the 20th century which ended at the end of the year 2000. year 2001 was the start of the 21st century which will end at the end of year 2100. got it?

years, months, days of the year, and days of the month are all 1-based. hours of the 24 hou systems, minutes, and seconds are all 0-based. hours of the 12 hour system are proxy 0-based with 12 substituting/proxying for 0.
