## Description

### Steps to reproduce

_Please write down the steps to reproduce. Try to write down all necessary preconditions (what permissions do you have, are other users involved?). Example:_

1.  log in as a user or an admin with permission to add a new task to my project
2.  Go to project "الأعمال اليومية" page then to "مجموعات العمل"
3.  Click on "انشاء حزمة جديدة"
4.  Type the name of the task and then the status
5.  try to add the start and end date

### What is the buggy behavior?

*   after selecting the start and end date on the calendar the duration is not calculated
*   after selecting the finish date, the start date changed automatically to become as finish date
*   when I click SAVE in the calendar an error message shows up as (Finish date لا تاريخ صحيح--يتوقع YYYY-MM-DD)
*   I tried to change the date format (all date format) and its the same problem
*   as a summary : the application can not deal with arabic date format as a start and end dates)

### What is the expected behavior?

_Describe how the application should behave like. Example:_

1.  The application should accept the Arabic date format and calculate the duration with no errors
2.  the application should accept thr finish date and not vheange it automatically.
3.  I recommend keeping the dates in English and not changing it to Arabic when the user changes the language interface since we are not using Arabic dates any more
