Why is no one in ember sure of the hour day of the week or year?

In "Ember in the Ashes" by Sabaa Tahir, the societal collapse and oppressive regime lead to a lack of structure and stability, causing the citizens to lose track of time. The constant fear, violence, and turmoil overshadow any sense of normalcy, making it difficult for people to focus on the passing of days and seasons. Additionally, the regime's manipulation of information contributes to this disorientation, further disconnecting individuals from the natural rhythms of life.
