Hi @Nabil_Servais,
Thanks for posting! Check out this thread.
You can use strftime from the Python datetime library to re-format the string any way you choose:
datetime — Basic date and time types — Python 3.12.0 documentation
That thread links to the documentation of datetime.date.strftime. Please read through their docs to learn how to change the format of the datepicker (from YYYY/MM/DD to DD/MM/YYYY).
There currently is no support to translate Streamlit widgets from English to French. Please submit a feature request in the Streamlit repo if you’d like for our engineers and community to consider it.
