Regular, planned Aeronautical Information Publications (AIP) as defined by the International Civil Aviation Organization (ICAO) are published and become effective at fixed dates.
AIRAC cycle definition as published in the ICAO Aeronautical Information Services Manual (DOC 8126; AN/872; 6th Edition; 2003). Test cases validate documented dates from 2003 until 2022. They also assert that the rare cases of a 14th cycle, e. g. in the years 2020 and 2043 are correctly handled.

This project provides a Julia library to deal with AIRAC cycle dates.
This project is not maintained by ICAO. Please use this project at your own risk.
AIRAC.jl is not currently a Julia registered package.
Currently only developer version is available. It can be installed by running Julia REPL:
