I think using libraries for such tasks would make deps dir too heavy and with reusing of Calendar strftime options Elixir codebase shouldn’t grow much. Currently I use regexes to check allowed dates of birth formats from depending on clients, eventually we can parse them to dt, I noticed many countries still haven't adopted ISO 8601 https://en.wikipedia.org/wiki/Date_format_by_country, so I just have a feeling it would be consistent and elegant if it would be it in Calendar especially if strftime produces formatted output. For instance %b format from strftime options could be reused to match exact range of abbreviated months from input and I think it should be pretty sufficient for parsing.
