The Chinese Calendar plugin enhances Obsidian by providing a calendar that displays information tailored to Chinese cultural practices, including lunar dates, festivals, solar terms, and public holidays. Users can toggle between month and year views, navigate through time periods, and create notes for specific dates or intervals like daily, weekly, monthly, quarterly, and yearly notes. The plugin integrates seamlessly with the Periodic Notes plugin for customizable file naming, templates, and folder settings. Additionally, it supports QuickAdd templates for advanced note creation, offering flexibility in capturing and organizing information based on calendar events.
