Select all the Tasks which you want to move to that date as well and drag & drop them in the group of the updated Tasks. Now when you open up one Task and change its Due Date, you’ll see a group for this date.

Grouping your Tasks by Due Date can be done in the following way: You can reschedule one of them and when you have your Task list Grouped By Due Date, you can move them all at once to that specific date. Is there any way to move all these tasks at once to a date one week after my return? Luckily, they were not critical for me to keep me from going on my Holiday anyway. I think I’ve been a bit too optimistic about what I can still achieve before my Holiday starts and now I have quite a few Tasks which are due for the end of the week which I won’t be able to finish.
