A quick way is to look at the magazine on the agenda.
You can see the agenda (see Agenda in Org Mode docs). Move the agenda to the desired period - day, week, month, year. Put it in log mode (using the "l" key described in section 10.5 "Commands in the agenda buffer" ). This will show for what period of time you work and when.
You can also use the hours table (see section 8.4.2 The hours table ) to get a detailed report in which you can set all the information about what interests you.
(Note: the heading numbers of the sections to which I refer are in version 8.2.5h in Org mode, your version may differ, but these sections will still be there)
