5. The Calendar
Urji Dhaha (UD) are seven or eight stars and constellations used by Ayyantus for time reckoning. Ayyantus are traditional astronomers. They stars make a somewhat linear formation in the sky. Triangulum comes first in the line of UD.
Around June, only Triangulum is visible early morning. The rest of UD are either out of sight at night, or they are blocked by day light. From November through March, the entire line of UD can be observed most of the night.
Bita Qara is the day in a year when full moon appears with Triangulum, while the other members of UD are not visible. Bita Qara happens in June. It is used as a reference date to define the cycle of a year.
Around March, most or all the line of UD is visible, but in late night the earth rotates out of sight.
