Reading the documentation of the ephemeris binding it sounded to me as if the holidays relative to Easter are not (yet) included. However they are! Maybe it is only me understanding it that way?
You can find the XML file for your country [here](https://github.com/svendiedrichsen/jollyday/tree/master/src/main/resources/holidays)
Looking into that file the holidays relative to eastern are named but in no obvious way calculated.
For further examples and other types of holidays that require more complicated calculations (e.g. holidays based on a lunar calendar, Easter, etc.) see the [XSD that defines the structures of the XML](https://github.com/svendiedrichsen/jollyday/blob/b78fa20e75d48bdf14e3fa8107befe44e3bacf3a/src/main/xsd/Holiday.xsd).
Since Easter is explicit mentioned I understood that Easter is not calculated.
Maybe the sentence in brackets should add look like: "(e.g. additional holidays based on a lunar calendar, Easter, etc.) " this.
But it still might be my personal misinterpretation!
This action works great! ThankYou!
