Forms datePicker does not work for the German month "March"

[Mergim Rexha]

Hello together,

I use Forms to create forms for our Jira Service Management and then provide the forms to our customers.

In one form I use two date pickers from the Forms Fields (checkScreenshot)



When a date is selected in the date picker which is in the month of March, the following message always appears:

Request could not be sent
You have not entered a valid date. Enter the date in the format 'd/MMM/yy' (e.g. '8/Feb/22').

Please Check Screenshot.

Now I have done some research and found out that there seems to be a problem with the German March, namely "März".
There are 2 or 3 tickets that I found:
[JRASERVER-62769] JIRA doesn't recognize "Mrz" abbreviation for March in German - Create and track feature requests for Atlassian products.

[JRASERVER-41268] JIRA doesn't recognize "Mrz" abbreviation for March in German - Create and track feature requests for Atlassian products.

In the comments it says the problem is solved, but I do not know if this also means for "forms", probably not or?

Then I also read that I need to adjust the settings in:

Settings -> “Advanced Settings”
jira.date.picker.javascript.format dd.MM.yyyy
jira.date.picker.javascript.format %d.%m.%Y
jira.date.time.picker.java.format dd.MM.yyyy HH:mm
jira.date.time.picker.javascript.format %d.%m.%Y %H:%M

System Settings -> “Look and feel”
Time Format HH:mm
Date Format EEEE HH:mm
Complete Date/Time Format dd.MM.yyyy HH:mm
Day/Month/Year Format dd.MM.yyyy
Use ISO8601 standard in Date Picker Yes

I have already done all this, but it still does not work. Can someone tell me something about this please?

Hello @Mergim Rexha,

Thank you for reaching out to the Atlassian Community!

I saw that you created a ticket with our support related to this question and they were able to replicate the issue.

Based on that, they raise a bug ticket:

• Forms doesn't submit from the customer portal when user set date to March and has Language set to German

I’m sharing this information here in case other community members face the same issue.

Kind regards,
Angélica
