The bulgar calendar is a way of keeping track of time that was used by the people of Bulgaria a long time ago. Basically, it's a tool that helps people know what day it is and how much time has passed since an important event like a holiday or a big celebration.
When we talk about time, we usually think about a year being made up of 12 months. But in the bulgar calendar, a year had 12 lunar months, which means they used the cycles of the moon to measure time instead of the sun. A lunar month is about 29.5 days long and it takes around 12.4 lunar months to make up one solar year.
What's interesting about the bulgar calendar is that it is different from the calendar that we use today. This is because it was based on a different set of beliefs and customs that were important to the bulgar people. For example, the bulgar calendar had several important days and holidays that were celebrated in different ways depending on the region and culture.
Overall, the bulgar calendar was an important tool that helped the people of Bulgaria keep track of time and stay in touch with their history and traditions. Although it's not widely used today, the bulgar calendar still has a special significance for people who value their cultural heritage and want to understand more about the customs and beliefs of the past.
