Date displaying differently after publication

[SBULL]

Hello

I have built a visual that uses a slicer. I want the date to be dd mmm yyyy as below, which it is in desktop when I have built the report.

For an unknown reason the slicer displays with the day in PBI browser, which is not desirable as it means the user can't actually see the date they are selecting.

Does anyone know why this is happening and how I can fix so that it displays the same as in the desktop?

Thanks in advance

This is a known behavior in Power BI Service: date slicers (especially dropdown ones) render differently than in Power BI Desktop. Specifically:

- In Power BI Desktop, the date format honors your model format or your system locale (dd mmm yyyy like 26 Mar 2025).
- In Power BI Service, dropdown slicers sometimes override that and display a long date format, like Wednesday, March 26, 2025, especially if the column is a DateTime or uses system locale defaults.

You need to force the desired format (dd mmm yyyy) across both Desktop and Service:

In Power BI Desktop, go to PQ editor, select your date column (Alt Fuel Bill date) and add a new column:

Alt Fuel Bill date (Formatted) = Date.ToText([Alt Fuel Bill date], "dd MMM yyyy")

Then use the new column in your slicer instead of the original date.

If you want to use DAX, you can create a new calculated column:

Formatted Date = FORMAT('YourTable'[Alt Fuel Bill date], "dd MMM yyyy")
