A
number of foreign scientists have shown interest in the Bulgarian Calendar since
1866 when there had been found and published two manuscripts of an ancient Bulgarian
chronicle called "A Namelist of the First Bulgarian Khans". Should somebody
then had guessed that a calendar that had been in use for thousands of years by
a people could not be ever erazed from the memory of this people, then the historical
science would have had its true and right decisions concerning the precise chronology
of Bulgarian history.
