This is because all the elements in DateType are bitfields of a Word. In C
you can actually divide one the integral data types into various fields in a
structure. So in the DateType you have:
typedef struct {
Word year :7; // years since 1904 (MAC format)
Word month :4;
Word day :5;
} DateType;
The whole struct consists only of one Word, and the year member takes up
7bits, month 4 bits and day 5 bits, for a total of 16 bits, hence 2 bytes.
