I want to change the format of date from MM-DD-YYYY
to DD-MM-YYYY
in list, Gantt charts etc. I have tried one option so far but it doesn't work properly which is explain below:
First option: I have change the regional and locale settings in the parent site. It helps to change the general date format such as when the document was created library. But it does not the change the format in Gantt Charts when we assign dates to a particular task.
