Jira date display messed up

[J]

I've got a task to change the date format in JIRA to yyyy/mm/dd. I changed the system settings to:

jira.date.picker.javascript.format=%Y/%m/%e

jira.date.time.picker.javascript.format=%Y/%m/%e %H:%M

jira.date.time.picker.java.format=yyyy/mm/dd H:mm

jira.date.picker.java.format= yyyy/mm/dd

Under look and feel, the format is is yyyy/MM/dd.

That worked to change the date pickers. Problem is, after you click off of the date picker, the month displayed is January no matter what the month is. I.e. if you pick 2022/02/01, the date displayed is 2022/01/01. 

Changing the date format under look and feel to yyyy/mm/dd did resolve this issue, HOWERVER it created a new issue: the issue creation date shows the month as 00 (i.e. 2022/00/01).

Is there a known solution to this?

Hi @J ,

welcome to the Atlassian community!

m is for minutes and M is for months. Probably this is cause of your issue.

Please try :

jira.date.time.picker.java.format=yyyy/MM/dd H:mm

jira.date.picker.java.format= yyyy/MM/dd

Hope this helps,

Fabio
