The first line simply adds 0 months to the `ymd`. If `ymd.month()` is 0, this will subtract one from the `year` and set the month to `Dec`. If `ymd.month()` is greater than 12, the year will be incremented as many times as appropriate, and the month will be brought within the proper range. This operation will do nothing if `ymd.month().ok()` is already true. The first line simply adds 0 months to the `ymd`.

The second line will "normalize" the day field. The second line requires that the month field is already normalized. For example `2015_y/dec/32` will become `2016_y/jan/1`.
