ELI5 (or an American) - European Soccer Schedule

I understand that each country has it's own league (la liga, EPL, etc) and that the Champions League are the top teams from each league.  But when is the Champions League played?  How do you get into the Champions League (is it like the postseason).  What happens during world cup and euro cup years?

Most 5-year-olds would have fallen asleep during the answers so far. Soccer schedules are ten times simpler than North American sports schedules. Here's what you need to know.

1. Champions League matches are played during the regular season.
2. Qualification for the Champions League is based on the previous season's performance in the national league.
3. The World Cup and European Championships are played every four years in the off season (i.e. summer). The European Championships are happening now. The next World Cup is in 2014.
