Package airac-java provides calculations on Aeronautical Information Regulation And

Control (AIRAC) cycles, i.e. cycle identifiers and effective calendar dates.

Regular, planned Aeronautical Information Publications (AIP) as defined by the

International Civil Aviation Organization (ICAO) are published and become

effective at fixed dates. This package implements the 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 1998 until

2020, including the rare cases of a 14th cycle, e. g. in the years 1976, 1998, 2020

and 2043.

## Example

```

Instant shalom = Instant.from(ZonedDateTime.of(2012, 8, 26, 0, 0, 0, 0, ZoneOffset.UTC));

String output = String.format("At %s the current AIRAC cycle was %s.\n",

    DateTimeFormatter.ofPattern("yyyy-MM-dd").withZone(ZoneOffset.UTC).format(shalom),

    Airac.fromInstant(shalom).toLongString());

System.out.println(output);

// Output:

// At 2012-08-26 the current AIRAC cycle was 1209 (effective: 2012-08-23; expires: 2012-09-19).

```

This is a port of my [go library](https://github.com/wjkohnen/airac/). I did this

port basically in order to learn how to use JSR-310 and parametrized JUnit tests.

## Wikipedia

Article on AIP / AIRAC cycles: https://en.wikipedia.org/wiki/Aeronautical_Information_Publication

There are wiki macros in that article that do basically the same thing as this

library. Though, this library does not trip over the case of 14 cycles per year

(e. g. 1998 and 2020).
