What you were looking for is `Dates.Year`, but that does not work the way you want it either because a number of days cannot be converted into years as years have a variable number of days.

Two possible solutions are:

```julia
julia> Dates.year(d1) - Dates.year(d2)
9

julia> Dates.days(d1-d2)/365.25
9.100616016427105

```
