Add Hints to Icons on Hover

[annikabudean]

Describe the current limitation
Hello!
When looking at the interface of the application it is not immediately clear what clicking the arrows and plus and minus buttons on each row does, as well as the right and left arrows on the top row.

Describe the proposed feature or enhancement
I believe it would be helpful to add a short hint to each of those buttons when a user hovers over them with their mouse. This way if a user is unsure about what these buttons do they can get a quick description. I see that this has been done with the "Go to Current Month" button as well as the "Switch View" button. Adding something like this to the buttons I mentioned would be helpful.

Additional context
The screenshots below show the buttons I am talking about.
