It's my understanding that this is [more of an elasticsearch feature](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-scripting.html#_lucene_expressions_scripts) that kibana happens to expose. I thought I read that timestamps adhere to the joda time interface but maybe elasticsearch only exposes a subset? If so, is there a reason why getDayOfWeek() was left out?
