I want weekly date_histogram function to start on Sunday in Kibana dashboards, but they currently start on Monday (ISO week). I’m using Kibana Lens with Elasticsearch 9.0.4. I’ve tried adjusting dateFormat:dow settings to Sunday and dateFormat:tz to Zulu (because my raw data value was 2025-10-05T14:14:54Z), but it still aggregates from Mon to Sun instead of Sun to Sat.
I did read some similar topics, but they did not talk about the visualization/lens charts, just the API approach.
