What is the differens between a ceiebration and a trodicen?

It seems there may be a typo in your question, as "trodicen" doesn't appear to be a recognized term. If you meant "tradition," then the difference is that a celebration is an event or activity meant to honor or recognize something significant, often involving joy and festivities. In contrast, a tradition refers to practices or customs that are passed down through generations, which may include various celebrations but can also encompass rituals, beliefs, and values within a culture.
