Some popular programming languages use month numbering which is off by 1 -- JavaScript comes to mind, as does Java, and if memory serves, C is another. I have some questions:
- If you are going to be ignoring the month numbering used by laypeople, then why not for the sake of consistency also ignore the day numbering used by laypeople, and number the days in each month starting from 0 ?
- Why is this so common?
- Whose idea was this in the first place?
