Replace date year

@set parts(person.birth) = (day=1, month=2)

I like this option. Thanks.

@jw3126

parts(d::Date) = (year=year(d), month=month(d), day=day(d))

Instead of defining parts we could, as indicated above, use the available Dates function getter: yearmonthday. Right?

Note that yearmonthday returns a Tuple and not a NamedTuple. So I prefer not to add extra magic to a setter that is not mirrored in the getter.
