NOTOC Year 788 (DCCLXXXVIII) was a leap year starting on Tuesday of the Julian calendar, the 788th year of the Common Era (CE) and Anno Domini (AD) designations, the 788th year of the 1st millennium, the 88th year of the 8th century, and the 9th year of the 780s decade. The denomination 788 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
