The Bulgarian calendar was a solar calendar system used by the Bulgars, who from the 4th century onwards dwelt in the Eurasian steppes north of the Caucasus and around the banks of river Volga. In 681, part of the Bulgarians settled in the Balkan Peninsula and established First Bulgarian Empire. The main source of information used for reconstruction of the Bulgarian calendar is a short 15th century transcript in Church Slavonic called Nominalia of the Bulgarian Khans, which contains 10 pairs of calendar terms. Additionally, the same dating system is used in a marginal note in a manuscript by 10th century monk Tudor Doksov and in the Chatalar Inscription by the 9th-century Bulgaria ruler Omurtag (), who also provides the Byzantine imperial dating equivalent (the indiction). According to the reconstructed calendar, the Bulgars used a 12-year cyclic calendar similar to the one adopted by Turkic peoples from the Chinese calendar, with names and numbers that are deciphered as in Bulgar language. Образуване на българската държава. проф. Петър Петров (Издателство Наука и изкуство, София, 1981) стр. 171. The reading, along with the "cyclic calendar" interpretation itself, was originally proposed by Finnish Slavist Jooseppi Julius Mikkola in 1913. Later, there have been various modifications and elaborations during the 20th century by scholars such as Géza Fehér, Omeljan Pritsak, Mosko Moskov and other scientists.Zlatarski, Vasil. 1918. Istoriya na balgarskata darzhava prez srednite vekove. Balgarsko letobroene (in Bulgarian).

Reconstructions vary slightly because some of the names are unattested, and the exact form of a few is debatable. The following list is based on Mosko Moskov's and description of the average mainstream interpretation, as well as his own reconstruction, and takes into account the existing disagreements:Именник на българските ханове – ново тълкуване.

Comparison with Turkic calendars

The following comparison table was made based on Omeljan Pritsak's analysis.Die bulgarische Fürstenliste und die Sprache der Protobulgaren. Otto Harrassowitz-Wiesbaden, 1955.

"puree", sensed. "biræg". But comparing the name of the year from the teleutic cycle circle, we see that "vereni" may be the tabu name for "dragon" = "rope" and be compared with chuv.
