**Option 2 (Slightly More Detailed):**

* **Description:** 用於分類和標示文章中提及的活動、會議、或其他事件的「開始時間」。方便讀者快速找到基於時間的相關資訊。 (Yòng yú fēnlèi hé biāoshì wénzhāng zhōng tíjí de huódòng, huìyì, huò qítā shìjiàn de “kāishǐ shíjiān”.

**Explanation of Considerations:**

* **WordPress Environment:** The descriptions cater to how a user would likely interact with a post tag within WordPress.
* **Clarity:** Each options aims to explain the meaning of “開始時間” (Start Time) and its practical purpose.
* **Search Engine Optimization (SEO):** All of the above description are in Traditional Chinese, which can help with indexing and search (if someone were to directly search for this phrase). You might consider adding a brief English translation in parentheses if your audience often uses both languages.
* **Target Audience:** Consider who will be using your website and tailor the wording to meet their needs and expectations (e.g. a more tech savvy audience vs. general public, etc.).

I recommend you choose the description that best fits the overall style and goals of your WordPress site. Good luck!
