《日历》是唐中期出现的一种官修史书,也是撰修《实录》的重要依据。受政局动荡和朝代更替的影响,唐五代《日历》的编纂时断时续,未有贯通,但在编修方式和修撰制度上有很大完善和发展,这为宋代《日历》全面、系统的纂修奠定了基础。 “Calendar” is a kind of official history book appearing in mid-Tang Dynasty, which is also an important basis for compiling “Record.” Due to the political unrest and the dynastic alternation, the compilation of “Calendar” in the Tang and the Five Dynasties was intermittent and impracticable. However, there was a great improvement and development in the compilation and revision system, System compilation laid the foundation.
