Depends on your target but log on at 8-9am, 11-12am, 3pm (this is when most of my targets are online). Then take note of how many that are online simply by counting. Do so everytime your online and you will start to see the pattern. In general the most people are online and active at 11am, 3pm and 8pm with 3pm being the biggest spike.
