How many days are there in a week?

A week consists of seven days: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, and Saturday. This structure is universally recognized in most cultures and is a fundamental aspect of the Gregorian calendar, which is the most widely used calendar system around the world. Understanding the seven-day week is important for effective time management, scheduling, and planning in various personal and professional contexts, including nursing practice. Recognizing this pattern supports nurses in their clinical duties, ensuring they are aware of deadlines, shift schedules, and patient care timelines.
