Describe the solution you'd like
Allow ranges longer than 7 days for the stats and log formats.

It would also be nice to allow a missing end of range to mean "today"

Is your feature request related to a problem? Please describe.
I need to invoice for hours since the last invoice was sent, and these periods vary depending on the project and the client. It would be nice to just put hours stats $lastinvoice... and get the total time spent on each project since that date.

Additionally, for tax purposes, I need to know hours spent on various projects over the course of a financial year (1 July to 30 June).

Describe alternatives you've considered
I currently just use the weekly interactive mode to walk the time period and use a calculator to sum the times. Not great.
