How to change my StartDay of the week on date slicer?

[fsantabarbara]

Hi everybody,

I'm using a data segmentation date slicer to filter my data with "between" format

Here a visual example (in Spanish):

I don't remember when but suddenly PowerBI changed the startDay of the date picker from Monday to Sunday (I live in Europe and we use Monday)

On this example 'dom' is Sunday in Spanish (domingo) and 'lun' is Monday (lunes)

Is it possibe to define the start day of the week on Monday as it was several weeks ago?

Thanks in advance,

   Fernando

Hi @fsantabarbara ,

This is a konwn issue (ICM: 301513764).

Microsoft Power BI removed an older calendar picker component and replaced it with the latest component used in other places in power BI. Product teams were not aware of this feature gap, but are already working on it. Because it will need testing, so please be patient. We do plan to restore locale-sensitive starting day of week.

Best Regards,
Winniz

We are in May 2025 and still the bug persists. Is there a way forward?

Thanks @amitchandak 

As @v-kkf-msft confirm, It's an internal bug. The date picker visual component suddenly changed.

This is the before and after bug situation.
