I'm facing the org.elasticsearch.index.mapper.MapperParsingException: failed to parse [date] - exception while loading the data to elastic search. The date format used is a date: MMM D, YYYY h:mm:ss A. The date value which I'm trying to load is Jan 3, 2019 4:34:34 PM. I' not sure what is wrong here. I feel date input is exactly matching the format. But it is still failing. I also tried using date: default format but it is also giving the same exception. ---

Please consult [https://www.joda.org/joda-time/apidocs/org/joda/time/format/DateTimeFormat.html](https://www.joda.org/joda-time/apidocs/org/joda/time/format/DateTimeFormat.html), referred here: [https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-date-format.html#custom-date-formats](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-date-format.html#custom-date-formats) For example, you should be using `a` instead of `A` for the AM/PM ---

As i have AM/PM values in capital i used A instead a. When i verified this format in Kibana - date format pattern, it was giving me the date as expected. I will try it with 'a' instead of 'A' to see if it works. I'm going through [https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-date-format.html#built-in-date-formats](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-date-format.html#built-in-date-formats). I think we should use strict date format always. It is mentioned that - ' For instance a date like `5/11/1` would be considered invalid and would need to be rewritten to `2005/11/01` to be accepted by the date parser.' I will try this option as well to see if it works. ---

I was able to format the date by referring to the website. I got the working date format YYYY-MM-DD'T'HH:mm:ss.SSS. I'm trying to add the Zone name (like CST) to the above date format by adding z. But YYYY-MM-DD'T'HH:mm:ss.SSSz is not working and I tried many variations but none of them are working for me. I was able to get the zone offset by using 'Z' but not Zone name. Is the date format with zone name is not supported in elastic search? ---
