[Feature Request] - Add tooltips

[margual56]

Is your feature request related to a problem? Please describe.
No

Describe the solution you'd like
Add a tooltip to the statistics explaining exactly what they are calculating. For example, some fields calculate 365 days, but others only take into account the remaining days until the end of the current year.

This is confusing and causes bad UX.

Describe alternatives you've considered
Improving the statistics' names, but if they are too long they may be even more confusing.
