If I had to infer, I'd say that an occasion can occur frequently. Occasions can be marked by specific circumstances and do not occur merely by chance. One can set up an occasion. An opportunity is based on chance and passing opportunities up is a decision that can lead to more regrets than an occasion. For example, you pass up the opportunity to become a professional sports player. This decision can lead to a lifetime of wonder based on "what could have been" where as occasions are less cherished because they might be recreated. For instance, you miss your friends birthday party. You're depressed for a short while, but you know that they will have a birthday party one year later. Also, an occasion can be set up by nearly anyone. One can set up a cocktail party or a trip to Europe. An opportunity to go to Europe however, would be different. Say you're offered a chance to travel Europe free of expenses because you had amazing grades in high school. That opportunity will not recur.
