Древният прабългяарски календар Колада
The ancient calendar Colada of the proto-bulgarians

Summary/Abstract: The paper considers the ancient Kolobursk Solar Calendar of the Proto-Bulgarians, which is characterized by its 10-month structure, 36 days monthly and 6-day weeks. The uniqueness of the calendar, named Colada, consists in leap year missing and compensating registrations by the kolobars on each 12th December, considered as a zero day of the year. Each compensation is with a 15-minute (ecliptic) duration and is not significant for people practically. The Solar Calendar of the Proto-Bulgarians has no beginning and finishes indefinitely in the future because it is adjusted annually and follows the rhythm of the Earth orbit around the Sun strictly.
