Background

The Thracian Calendar and External Influences (1st Millennium BC - 1st Millennium AD)

• The Thracians, who inhabited parts of ancient Bulgaria from around 1200 BC onwards, might have used a lunar calendar with possible solar elements.
• Limited archaeological evidence and historical records make it difficult to reconstruct the exact details of this calendar. However, scholars believe it likely incorporated lunar cycles for months and potentially tracked the solar year for agricultural purposes.
• As Greek and Roman empires expanded, their influence reached Bulgaria. The Romans introduced the Julian calendar, a solar calendar with leap years, around the 1st century BC. This calendar offered a more standardized system compared to earlier practices.

The Rise of Christianity and the Byzantine Calendar (1st Millennium AD)

• The spread of Christianity from the 4th century AD onwards brought a significant shift in timekeeping.
• The Byzantine calendar, a variant of the Julian calendar adopted by the Eastern Roman Empire (Byzantium), became the dominant system.
• This calendar incorporated the Julian system for months and years, but also included important Christian holidays like Christmas and Easter. These religious holidays became crucial reference points for people throughout Bulgaria.

The Bulgar Calendar and the Merging of Traditions (7th-10th Centuries AD)

• The arrival of the Bulgars, a Turkic people, in the 7th century AD introduced a potential complication. They might have had their own 12-year cyclic calendar, possibly based on both lunar and solar cycles.
• Scholars believe there may have been a period of using both the Byzantine calendar, essential for religious purposes, and the Bulgar calendar, used for specific cultural traditions. Over time, these traditions likely merged, with elements of both calendars influencing timekeeping practices.

Ottoman Rule and the Islamic Calendar (14th-19th Centuries)

• The Ottoman conquest of Bulgaria in the 14th century introduced the Islamic lunar calendar for administrative purposes.
• The Islamic calendar is based on lunar cycles and differs significantly from the solar-based Julian calendar. This meant the start of months and years shifted based on the phases of the moon.
• However, the Christian calendar with its religious holidays remained important for the Bulgarian population. People likely continued to use a combination of calendars depending on the context, highlighting the complex layering of timekeeping traditions.

Standardization and the Gregorian Calendar (19th-20th Centuries)

• With Bulgaria's liberation from Ottoman rule in the late 19th century, the nation adopted the Gregorian calendar in 1878.
• The Gregorian calendar, a more accurate version of the Julian calendar, addressed a slight drift that had accumulated over centuries.
• Adopting the Gregorian calendar brought Bulgaria in line with most of Europe for civil purposes, ensuring consistency in record-keeping and communication.
