The captions in this report are misleading. While they seem to refer to calendaric day, week, month or year, they actually don't. Instead they refer to the period of the last 24 hours, last 7 days and so forth. It becomes messy for month and year then, as they vary in length.

I'd suggest to change the captions to something like:

• Last 24 hours
• Last 7 days
• Last 30 days
• Last 365 days
