What would you name the last of the five seasons?

In your world, there are five seasons. The four traditional ones, plus one more, and you can't really tell why that one is there, but it's a very important season, and you don't want it to disappear.<br><br>I am writing a story about these seasons, and I want to name the mysterious fifth season. I would prefer that the name be in the world's language, not English. It could be the name of the season, or an acronym, or a phrase that describes it. If there is any relevant context, it would be good to know.<br><br>* **Duration**: The fifth season is about three months long, and lasts about half the year, so it is not a holiday, or a weather anomaly.<br>* **Climate**: It is very similar to autumn in most of North America. In the world, this season is dry and cool in most places, but with a few exceptions. The weather is similar to what we would have if our autumns lasted longer. It is a time of harvest, and harvest festivals.<br>* **Other details**: In many places, the fifth season is the season of change. It is the time of year when babies are born. It's a time for renewal. It's a time for transition.<br>* **Name**: The season is called by many names. People talk about it in hushed tones, and refer to it by code names, or acronyms. It is also called by the name of a tree. There are some who refer to it by its color, and some who use a phrase.<br>* **Examples**: **Bloom**. **Harvest. Yellow season.** The **Maple Season**. The **Transition Season.** The **Season of Renewal.**<br><br>What would you name this season?
