Assumption we are talking simply about when the hour first is approached - i.e. what o'clocks do the hands form obtuse angle.

If it is a 12 hour clock then the answer is every hour after 3 o'clock and before 9 o'clock, i.e. 4 o'clock, 5 o'clock, 6 o'clock, 7 o'clock, 8 o'clock.

If it is a 24 hour clock (they do exist) then the answer is every hour after 6 o'clock and before 18 o'clock, i.e. 7 o'clock, 8 o'clock, 9 o'clock, 10 o'clock, 11 o'clock, 12 o'clock , 13 o'clock ,14 o'clock ,15 o'clock , 16 o'clock , 17 o'clock
