I'm trying to parse my JSON data in the logstash config and send the JSON to elasticSearch depending on the week. My data fields has the specific date.

Example: I have a date:"MM-DD-YYYY" as a field in the JSON, but I want to send to an index based on the week, so index should be something like "Week of 06/20".
