How to sort column by date in Numbers?

I've my column in format dd/mm/yyyy and I would like to sort them by date. But I can't find any way of sorting the column by date. If I Sort Ascending, it doesn't recognise that the rows have the date formats. Any easy way of doing that?

Your dates might not be recognized as dates by Numbers.

In my case, Numbers does not offer dd/mm/yyyy as one of the standard date format and I have to define a custom format for that pattern. (Not sure, if that applies in your case: The date must be entered according to your locale settings - I can set "dd/mm/yyyy" as the date format, but I have to enter it as "dd.mm.yyyy" on my German system.)

Using the sort & filter window then works well on the formatted dates.
