To accommodate worshipers attending the five daily prayers, mosques are typically open from before sunrise to two hours after sunset—but the imam may not be present for the entire day. A typical full-time imam works 40 to 50 hours a week. In the United States, mosques also serve as community centers, and the imam may be responsible for organizing non-religious classes and activities.
This job can sometimes be stressful because of the low pay, heavy demands by congregants, and low levels of staffing at mosques.
