The Baha'i calendar, known as the Bad (which means "wonderful"), is divided into nineteen months, each with nineteen days.
- In normal years, four intercalary days — known as AYYAM-I-HA, or the Days of Ha — come after the eighteenth month, while five are added in leap years.
- The sum of 19 multiplied by 19 = 361, plus four intercalary days equals 365.
- However, the number nineteen was selected for reasons other than its mathematical use.
Mirza Ali Mohammad (commonly known as the BAB), the Baha'i faith's first prophet, created a calendar for the new religion.
He had eighteen disciples, thus the calendar's structure remembers the nineteen original Babis.
- The regular Baha'i worship gathering is the Nineteen-Day Feast, which takes place on the first day of each month.
- The three-part structure of each Feast is the same: prayer, congregational business, and fellowship over a shared meal.
- The Baha'i year starts on March 21, the spring equinox.
- The years of the Baha'i faith are running out.
- The first year was 1844, which was the year of the Bab's Declaration.
