Hi everyone, In my Pega Constellation application, the date format is controlled by the operator’s locale. For example, setting the locale to `en_CA` displays dates in `yyyy-MM-dd` format. My requirement is to display dates in `MM/dd/yyyy` format while keeping the locale as `en_CA`. Is there any OOTB configuration to customize the default date format for a specific locale across the application, without updating individual views or date fields? Any suggestions would be appreciated. Thank you! ---

In Constellation, date formatting is primarily driven by the user’s locale and the browser’s internationalization settings. The platform is designed to display dates according to the locale conventions (for example, en\_CA → yyyy-MM-dd, en\_US → MM/dd/yyyy). Another potential option to consider to use DX Component. ---

Hi @RameshSangili Thank you for the detailed explanation and for suggesting the DX Component approach. This is very helpful and gives me a better understanding of how Constellation handles date formatting. ---

You can override the display of the date? perhaps that give you enough control to manage the expected outcome without resorting to DX Components? You could put medium or long, that would avoid any confusion about date formats… ![image](https://pega1.discourse-cdn.com/pega/original/3X/6/6/66c9641e317f4b3ca0f7c72826d2220ddb019038.png) ---

Hi @MarcCheong Thank you for your answer. Your suggestion is valid, but in my scenario, the application supports multiple regions, including the US, EMEA, and Canada. The US and EMEA date formats differ from the Canadian format, and the current configuration works based on the local settings, except for Canada. If I change the view to use a medium or long date format, it will also affect the date display for the other regions. Therefore, I’m looking for a solution that supports region-specific date formats without affecting the existing configurations. ---

Hello @Eranda_Weerasingha The left over option is to write a custom DX component extending the OOTB one. I have already replied to a similar question in the below post sometime back. > [@Display Date format as YYYY/MM/DD in Constellation 25.1.1 without using custom component](https://forums.pega.com/t/display-date-format-as-yyyy-mm-dd-in-constellation-25-1-1-without-using-custom-component/10416/2): > > @krishnamohan Pokala As you already mentioned; Set the locale in the operator record to the correct one and the user will see it in all places on the UI. I think Pega here does exactly what you may expect: it respects the users preferences on date and date/time formats. So if a user enters something in EU, most likely the input will be DD-MM-YYYY, and someone reading/changing it in the Canada will see YYYY/MM/DD. Optimal UX for both persona’s. Kindly have a look at it. Hope it helps Regards JC
