Converting Date Formats from dd/mm/yyyy to yyyy-mm-dd

Could someone help with the correct code to convert date formats as follows. The simple code throws an error at line Date_2 = … :

#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)


See Dates.format:

julia> Dates.format(Date_1, df)

Many thanks for quick respone. Works
