Expand description
Calendrical calculations
This crate implements algorithms from Calendrical Calculations by Reingold & Dershowitz, Cambridge University Press, 4th edition (2018) as needed by ICU4X.
Most of these algorithms can be found as lisp code in the book or on GithHub.
The primary purpose of this crate is use by ICU4X, however if non-ICU4X users need this we are happy to add more structure to this crate as needed.
