24/7 if done correctly. Have a look for some guides for your motherboard. Read what they are doing and take it step by step, little by little.
You can't do any damage as long as you keep voltages within a reasonable level (more volts = more heat = damage)
Keep it below 60c, keep vcore no higher than 1.4v and take it bit by bit. Stress test in between each change (using prime95 or similar). Always overclock using the bios (not a program).
If you change something and it doesnt boot, reset cmos by taking the battery out for a bit, do some power cycles, put it back in and you should be fine.
I started by following a guide and picking it up as I go along. Slow and steady.
Got my Q6600 (oldish) to 3.4ghz 24/7 now and still have no reason to upgrade
Same with my 5850 graphics card. Overclocked the pants off it!
