I am not super convinced of the usefulness of all these methods. My reason is that there are all kinds of operations someone may want to do on dates. Where do you draw the line?
But then you would also want Would similar methods on |

Using an i16 ties into your work in #882. But maybe it is best to accept an i32 until the decision is made to restrict the range of allowed years?

This might fail if year == MAX_YEAR.

This might fail if year == MAX_YEAR && month == 12.

Closing. I would be interested to have a method to easily create a |
These functions are to reduce the number of unwraps needed when creating NaiveDates
