Because all we know is that the earlier limit for her date of birth is January 2, 1979 and that the later limit for her date of birth is December 31, 1980 - that her date of birth can only fall in that range, but could fall at any point in that range, that means when she died in Spring 2018 she was absolute minimum 37 and absolute maximum 39. Not 37-38.
