# Kairos
Calculate times with chrono "plain text like" in Rust.

From Wikipedia:
> Kairos (καιρός) is an Ancient Greek word meaning the right, critical or
> opportune moment.
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.
