## What is Today in History?

Today in History is a historical event lookup tool built on top of the Wikipedia open knowledge base, designed for researchers, teachers, students and content creators.

■ Data Coverage
• Full 365-day calendar coverage
• Bilingual (Chinese / English) event text
• Time span from BCE to present
• Seven-category taxonomy: Politics, Science, Culture, Sports, Art, Technology, Disasters
• Two regional dimensions: China / World

■ Data Source & Update Mechanism
Event titles and summaries are pulled directly from the official Wikipedia On-This-Day API. Each visit to a date refreshes both Chinese and English versions, indexed by year and de-duplicated. All events are sorted in ascending chronological order for clean timeline analysis.

■ Engineering Features
• Three-tier cache: memory then on-disk (24h TTL) then bundled fallback
• Offline degradation: switches automatically to the local library on network failure
• Parallel fetch: Chinese and English endpoints requested concurrently, around 50 percent faster load
• Incremental index: calendar view shows real-time dot indicators for days with events

■ Search & Filter
• Multi-category intersection: combine any subset of seven categories
• Region select: China only / World only / All
• Full-text fuzzy search: matches keywords across titles and bodies in both languages
• Calendar jump: tap any date to load instantly

■ Use Cases
• History lesson preparation by date
• Academic research and timeline construction
• Topic ideation for newsletters, videos, podcasts
• Student homework and exam review
• General reading and daily knowledge accumulation

■ Specs
• Devices: iPhone
• Minimum OS: iOS 17.0
• Languages: Simplified Chinese / English
• App size: lightweight
• Network: online for live data, offline for cached and bundled content

■ Privacy & Compliance
• No personal identifiers collected
• No third-party tracking SDKs
• All cached data stays on device
• No in-app purchase, no subscription, no ads
• Network traffic limited to wikimedia.org public API

A reliable source. Clean retrieval. Strict privacy. Today in History is the desktop reference tool for every history-conscious workflow.
