Calendar planning app (drag and drop tasks)

[Nameynamechangeforthis]

I'm looking for an online calendar that I can organise my teams work into.

We have loads of projects in the year so I want to be able to plan what we do and when for 2020 so they don't overlap.
What I basically am trying to find is a calendar where I can drag and drop colour coded tasks until I come up with a plan for the year that works.

There are about a million to-do list and calendar planners but can't quite find what I'm looking for.

Any suggestions?!

Have a look at TimeTree. I'm not sure about dragging and dropping but you can have multiple calendars and colour code

Thanks Daffodil

Just had a quick look and looks useful but unfortunately it doesn't have the option to view the whole year.

I would like to be able to view the whole of 2020 at once ideally
