Because the underlying structure used to represent DateTime is a struct, which is simply a map under the hood. Erlang/Elixir uses a rather arbitrary order of keys (e.g. hour -> year -> day -> minute) when comparing 2 maps which you can't control.
Thus, you need to have a specific function that would compare these structs according to implied field order (year -> month -> day -> hour -> etc.) More: https://hexdocs.pm/elixir/main/NaiveDateTime.html#module-comparing-naive-date-times On Thursday, 2 March 2023 at 4:38:00 pm UTC+1 cbw...@gmail.com wrote: > Can't you compare DateTime with '>' or '<' instead of DateTime.compare? > -- You received this message because you are subscribed to the Google Groups "elixir-lang-core" group.
