Description

Automatically maintain a multi-stock event calendar for investors: 1. Fetch financial reports, dividends, lockup expirations, index adjustments, macroeconomic data, and holidays online, generating structured tables and an interactive HTML calendar. 2. Support three modes: view, refresh, and add/delete stocks, with incremental updates that do not overwrite history. 3. After the first generation, the HTML page reuses its structure; subsequent updates only modify the embedded event data JSON.
