Could someone help with the correct code to convert date formats as follows. The simple code throws an error at line Date\_2 = … :

```julia
#Change Date formats
using Dates

Start_Date = "2000-02-01"
Date_1 = Date(Start_Date,"yyyy-mm-dd")
println("Date_1 ...", Date_1)

df = Dates.DateFormat("dd/mm/yyyy")
Date_2 = Date(Date_1,df)
println("Date_2 ..", Date_2)

```

thanks

See [`Dates.format`](https://docs.julialang.org/en/v1/stdlib/Dates/#Dates.format-Tuple%7BTimeType,%20AbstractString%7D):

```julia
julia> Dates.format(Date_1, df)
"01/02/2000"

```
