常年

常年 means 'all year round' or 'perennially,' describing something that happens continuously throughout the year without seasonal change.

The character 常 (cháng) means 'usual' or 'customary,' and 年 (nián) means 'year.' Together, they convey the idea of something that is consistently true or occurs throughout the entire year.

常年 is often used to describe weather, natural phenomena, or habits that persist without variation. It's commonly seen in contexts like climate descriptions, product usage, or long-term trends. For example, it can be used to say a place has constant temperatures or that a service is available all year.
