As part of its effort to connect national history with world history, "The Academia Historica is largely using Western dates, although it does provide notes with the reign periods traditionally used in Chinese history. The practice will help foreign readers gain understanding about our nation's history, and it will remind all those researching and writing ROC and Taiwanese history that one needs to make connections between these histories and world history."
而為了著重國史與世界史的銜接，「國史館的歷史紀年將以西元為主，其後再加註當時統治政權的年號，如此可方便國外讀者瞭解我國的歷史，且提醒任何國史研究或敘述者，務必留意與世界史相互激盪的一面。」
