From Wikipedia:

This library offers an abstraction over the awesome `chrono` crate to
calculate dates almost like one would write plain text:

```rust
// get the end of the month of the day 5 days ago
let _ = (today() - week(1) + days(2)).end_of_month();

// alternative to above
let _ = (today() - days(5)).end_of_month();

// get the name of the day of the end of the current year
let _ = today().end_of_year().dayname();

// get a vector of dates for the next 4 weeks, starting today
let _ = today().every(week(1)).take(4);

// get an iterator of dates for the next year, in a weekly fashion, starting
// today but skipping october
let _ = today().every(week(1)).skip(Month::October).until(Mark::END_OF_YEAR);

// and finally, a complex one

let _ = (today() - year(1))                // exactly one year ago
  .every(Day::Monday)                      // and then every Monday
  .skip(Month::October)                    // but not in october
  .skip(|date| date.is(Mark::MONTH_START)) // and not if the day is the 1st of a month
  .until(Mark::Moment(today()));           // until today
```

Plus, we want to offer a string-parser which can be used to parse user input
into such things. This will be a compiletime option to include the parser or
not.
