Power Automate understands my dates wrong

Hi everybody


ok so I have a weird problem with my dates format in PA. Power automate keeps "understanding" my dates in US format.


In a very simple flow I create a compose action with "10/05/2022" for exemple. Since my Microsoft account is set to display dates in "dd-MM-yyyy" I expect power automate to read this as 10th of May 2022 however it always understands it as 5th of october.

So in this simple flow I plug the output of the first compose action (10/05/2022) in an other compose action and use the expression "formatDateTime" with the dd-MM-yyyy format, and it systematically returns "05/10/2022".

The problem is that when I put 15/05/2022 in the first compose my flow fails and I get this message


InvalidTemplate. Unable to process template language expressions in action 'Compose_2' inputs at line '0' and column '0': 'In function 'formatDateTime', the value provided for date time string '15/05/2022' was not valid. The datetime string must match ISO 8601 format.'.


This is annoying as I work with documents only using the dd-MM-yyyy format, that most of the time are only strings... which means I get the wrong format or an error every time I'm dealing with dates.


Any idea of how I can get Power Automate to understand my dates properly? I have been checking some solutions on the forum but so far none was able to fix this.


Thanks in advance, y'all have a good one

I've got the same annoying issue. No fix found yet 😞

Try this--formatDateTime(body(‘Get_item)?[‘StartDate’], ‘yyyy-MM-ddThh:mm:ssZ’)
