Hi @iamthealex,

I'm thinking you can make a scripted field to convert the date to a number, then use that in the Visual Builder.

See this post for more information [[scripted field] convert String date to timestamp](https://discuss.elastic.co/t/scripted-field-convert-string-date-to-timestamp/94885)
