===== Core Meaning =====
  * **Pinyin (with tone marks):** zhōunián
  * **Part of Speech:** Noun
  * **HSK Level:** HSK 4
  * **Concise Definition:** A full year; an anniversary marking the completion of one or more years.
  * **In a Nutshell:** **周年 (zhōunián)** is the direct and most common way to say "anniversary" in Mandarin Chinese. It literally means "cycle year," emphasizing the completion of a full 365-day cycle. It's used for happy occasions like weddings and company foundings, as well as for more somber remembrances of historical events. The key is that it always refers to a period of one or more full years.
===== Character Breakdown =====
  * **周 (zhōu):** This character means "cycle," "circuit," or "week." Pictorially, it's thought to have originated from a depiction of a field with a path around it, symbolizing a complete lap or circuit.
  * **年 (nián):** This character simply means "year." Its ancient form is said to depict a person carrying harvested grain on their back, representing the annual harvest cycle which defined a year.
  * Together, **周年 (zhōunián)** combines "cycle" + "year" to literally mean "a full cycle of a year." This elegantly captures the concept of an event's date coming around again after a full year has passed.
===== Cultural Context and Significance =====
In Chinese culture, marking a **周年 (zhōunián)** is an important way to show respect for the past and celebrate endurance. While personal anniversaries like weddings are celebrated, company and national anniversaries often take on a much larger public significance.
A key cultural and linguistic point is the distinction between **周年 (zhōunián)** and **纪念日 (jìniànrì)**.
  *   **周年 (zhōunián):** Specifically means an **annual** anniversary. It marks the completion of a year. You can have a one-year, five-year, or ten-year **周年**.
  *   **纪念日 (jìniànrì):** Is a much broader term meaning "commemoration day" or "memorial day." It can be annual, but it doesn't have to be. For example, a couple might celebrate a 100-day **纪念日**, but they would never call it a **周年**.
Think of it this way: In English, we might casually say "our six-month anniversary." In Chinese, this is incorrect. You would use **纪念日 (jìniànrì)**. All **周年 (zhōunián)** are a type of **纪念日 (jìniànrì)**, but not all **纪念日 (jìniànrì)** are **周年 (zhōunián)**. This reflects a more precise way of thinking about time and milestones.
===== Practical Usage in Modern China =====
**周年 (zhōunián)** is a versatile noun used in both formal and informal contexts, though it carries a slightly more formal weight than casual conversation.
  * **Relationships and Weddings:** It's very common to talk about wedding anniversaries. You'll often see it preceded by a number and the type of event.
    * `结婚十周年 (jiéhūn shí zhōunián)` - 10th wedding anniversary
    * `我们恋爱一周年了 (wǒmen liàn'ài yī zhōunián le)` - It's our first anniversary of dating.

    * `本店一周年，全场八折！ (běn diàn yī zhōunián, quánchǎng bā zhé!)` - It's our store's 1st anniversary, 20% off everything!

    * `汶川地震十周年 (Wènchuān dìzhèn shí zhōunián)` - The 10th anniversary of the Wenchuan earthquake.

===== Nuances and Common Mistakes =====
The most common mistake for learners is confusing **周年 (zhōunián)** with the broader term **纪念日 (jìniànrì)**.
  *   **Mistake:** Using **周年** for a period shorter than a year.
    * **Incorrect:** 我们在一起六个月**周年**了。(Wǒmen zài yīqǐ liù ge yuè **zhōunián** le.)
    * **Reason:** **周年** explicitly means "cycle **year**." Six months is not a year.
    * **Correct:** 我们在一起半年了。(Wǒmen zài yīqǐ bànnián le.) - "We've been together for half a year."
    * **Correct:** 今天是我们的六个月**纪念日**。(Jīntiān shì wǒmen de liù ge yuè **jìniànrì**.) - "Today is our six-month commemoration day."
  *   **Mistake:** Using **周年** as a verb.
    * **Incorrect:** 我们明天要**周年**了。(Wǒmen míngtiān yào **zhōunián** le.)
    * **Reason:** **周年** is a noun, not a verb. In English, you can't "anniversary" something. You "celebrate" or "commemorate" an anniversary.
    * **Correct:** 明天是我们的**周年**纪念日，我们要去庆祝一下。(Míngtiān shì wǒmen de **zhōunián** jìniànrì, wǒmen yào qù qìngzhù yīxià.) - "Tomorrow is our anniversary, we're going to celebrate."
