Answer 2

This is a frequent question on the joda time mailing list and the usual answer is to try RFC 2445. Disclaimer: I have not used it myself.

Answer 3

Check out Lamma date (I wrote it recently), which is designed to generate dates based on a recurrence pattern.

For example:

import static io.lamma.LammaJavaImports.*;
Dates.from(2010, 1, 1).to(2019, 12, 31).byYears(3).on(Locators.nth(3, FRIDAY).of(FEBRUARY)).build();

will generate the third Friday of February for every 3 years in 2010s

Output:

List(2010-02-19, 2013-02-15, 2016-02-19, 2019-02-15)
