How do i add a task due from date X to date Y ?
you can set up a recurring task using one of the date formats listed here: https://todoist.com/Help/timeInsert and add "starting 1. jun" for example to declare the first occurrence.
However, you cannot set an ending date right now, but we will consider adding such option in the future. You're welcome to add your vote to these requests:
