I'm starting to use the new Preview actions for Planner such as "Create a task" and one thing that I had to do a good amount of research on was formatting the correct date format for Start and Due dates to work appropriately.

It would be nice not to have to dive into WDL in order to get a valid date. Maybe some operations or flexibility in actions that require date formatting to allow for easier use?
