This module recalculates Task start/end dates depending on Project start/end dates.
This addon requires Odoo v8 after 2015-08-24 because is not fully functional without this patch: Odoo PR #8208
You can define working calendar at Setting > Technical > Resource > Working time Then assign this calendar to a resource (related with an user), a project or a company
When calculating task dates, this addon will look for a working calendar in this order:
- If project has working time assigned, use it.
- If user assigned, search first resource related with this user (normally user is related, only with one resource) and get its working calendar ends at 18:00
- If not user assigned or resource hasn't working calendar, search first working calendar of the company
- If no working calendar found, then every day is workable and work starts at 08:00 and ends at 18:00
Also you can define which task stages are included in recalculation when 'Project recalculate' button is clicked. By default, all are included. To change this go to Project > Configuration > Stages > Task Stages and change 'Include in project recalculate' field
There are two calculation modes:
- Date begin: Task start/end dates are recalculated from project's date begin
- Date end: Task start/end dates are recalculated from project's date end
If the project start/end date is changed in the form view, then you have to click "Recalculate project" button to recalculate all open tasks  according to the new date.
 'Open tasks' means tasks in a stage that are defined with 'Include in project recalculate' = True
This a typical use case:
- Create a project and configure:
- Calculation type, for example "Date end"
- Date end
- Create tasks, configuring for each one:
- From days, in this example, days from date end when this task must start
- Estimation days, duration of the task in days
- Click at "Recalculate project" button.
- Go to task list in Gantt view and see the recalculated planning
