Not able to set the aui datepicker format that are used by Jira look & feel dateformats

Hi all,

Problem:
Not able to set the datepicker format that is used by Jira look & feel date formats

I have the requirement that set the date picker format that is used by Jira look & feels date formats
I got the look & feel date format by using the Rest API as below mentioned and set that format to date picker. However, I am not able to use the exact date format. Is there way to use the same formats that are used by jira look & feel date formats.

ex:
Jira date format: dd/MMM/yy - 09/Jun/20

date picker format: dd/MMM/yy - 09/JuneJun/2020 (this is an issue if I set the same format)

Blockquote
/rest/api/2/application-properties?key=jira.lf.date.dmy

Jira version: 7.10.x

I appreciate all your opinions and suggestions.

Thanks
Kiran. M
