One library I really need to get back to working on while on vacation is Holidays. There haven’t been any updates to its content for quite some time. Now I have added the holidays for Poland, the Netherlands, Belgium, and Denmark.
For Belgium, the holidays for the three communities were each added to a sub-division, and the Iris Festival was added to the UN/LOCODE BE BRU.
The library can be found on Maven Central:
<dependency> <groupId>de.schegge</groupId> <artifactId>holidays</artifactId> <version>1.2.0</version> </dependency>
If there are any errors regarding the holidays, please open an issue on the project page at https://gitlab.com/schegge/holidays.
