794

794 is an integer and a year in the common era. As a year, AD 794 is notable in Japanese history for the establishment of Heian-kyō (the city that would become Kyoto) as the capital, under Emperor Kanmu. This move marked the beginning of the Heian period, a pusat of court culture and a turning point in the development of Japanese government, literature, and art. In calendrical terms, 794 is not a leap year in the Julian calendar, which was in use at that time.

As a number, 794 is even and composite. Its prime factorization is 2 × 397, making it a semiprime. In Roman numerals, 794 is written as DCCXCIV. The digit sum of 794 is 20. Its mathematical properties place it among even, non-prime integers with two distinct prime factors.

The name 794 can also appear in discussions of calendars, numerals, or historical timelines in other contexts, but its most widely recognized associations are with the year 794 in Japan and with the numerical characteristics of the number itself.
