Hi Guys, When we apply the weekly aggregation, we consider the key as start day of the week and the key\_as\_string is returned as per that. Is there any possibility to return the key\_as\_string to be 'start\_day\_of\_week - end\_day\_of\_week'? Regards, Chandan ---

> [@Chandan\_PR](#): > > Is there any possibility to return the key\_as\_string to be 'start\_day\_of\_week - end\_day\_of\_week' I don't think it is currently possible since the `key` (and also `key_as_string`) is solely intended to be a bucket identifier, not something that is intended for direct use in a graph, for example. I came across this [issue](https://github.com/elastic/elasticsearch/issues/9528) recently which talks a bit about scripted formatting of this, but I don't think this has really made it as a feature request yet. ---
