date format in slicer

I remain annoyed that this date format cannot be changed in the slicer's formatting options. Many years before Power BI was even a thing, my company standardized on ISO date format (YYYY-MM-DD) for all reporting to resolve misinterpretations across our international business. Now, I create Power BI reports that are embedded in a corporate web application and am constantly asked why the slicers have the "wrong" date format. Report designers need to be able to control this sort of thing regardless of the user's regional localization settings at the OS or browser level.

I have tried evetything.  

Changed regional settings. Changed date formats. Changed locale. etc. 

I need my format to be on slicer DD/MM/YYYY  and calendar should start with monday. 

But it ise still MM/DD/YYYY and starts with Sunday. 

There is no logic.  

When I changed my date format in power bi the the same formar should be on all the visualizations. 

In table I have it in correct format but in slicer not.    WTF?

Like many others, I cannot get this to work as described. I suspect it is a bug in the  slicer. 

Besides which, I am using powerautomate to produce a PDF report, which date format will this use? I cannot get powerautomate exported version to display anything other than mm/dd/yyyy which is  a huge problem as these reports as supposed to go to customers.

Can anybody definitevly solve this problem so that we can fix the date format for a slicer and not have the system attempt to be "helpful" when it is not wanted.

it's only works on PowerBI Desktop, but when we check it on "https://app.powerbi.com", it's still show date with "MM/DD/YYYY" format, not "DD/MM/YYYY"
 

Hi all,

I am having the same issue here. Power Bi service forced all the date slicer in all of my report into the US format, 'MM/DD/YYYY'. Should not related to any OS nor broswer setting, all the date slicer was displaying in 'DD/MM/YYYY' format last week. 

Any update ?

Cheers,

Yep, I see the same thing. What locality are you? I'm English (US). I see the same thing. You change the date format to something like dd/mm/yyyy and in the slicer it shows as mm/dd/yyyy but in other visuals it displays as dd/mm/yyyy (like table)

If you have somehow changed the date format within the slicer itself, and regardless of the date format you change the source data to, it will still not update. It's likely because you have accidentally or unintentionally grouped the dates somehow. This happens automatically in many cases when placing the date field in other pivot sections. 

To revert to the original date format, drag the Date field back into the rows, then right-click and select Ungroup. Now your date should be back in its original format. Now you can insert the slicer, and the date will be in your correct (original) format.
