# Dates When working with dates in Elixir, nerver use "<" or ">", because sometimes, it will not work the way you want ```elixir iex(16)> first = Timex.parse!("Tue, 29 Oct 2019 16:00:00 +0000", "%a, %d %b %Y %H:%M:%S %z", :strftime) #DateTime<2019-10-29 16:00:00+00:00 GMT Etc/GMT+0> iex(17)> second = Timex.parse!("Wed, 06 Nov 2019 23:00:00 +0000", "%a, %d %b %Y %H:%M:%S %z", :strftime) #DateTime<2019-11-06 23:00:00+00:00 GMT Etc/GMT+0> iex(18)> first < second false ``` # [Timex](https://hexdocs.pm/timex/Timex.html) For example, with `Timex` comes the `compare` function. ```elixir Timex.compare(first, second) -1 ``` And return value should be considered as follow : - -1 : first is before second - 0 : first is equal to second - 1 : second is before first
