Final answer:
The statement is false; the getDate() method retrieves the day of the month. The getDay() method is used to obtain the day of the week, ranging from 0 (Sunday) to 6 (Saturday) in JavaScript.
Step-by-step explanation:
The statement that the getDate() method in a calendar app returns an integer ranging from 0 (Sunday) to 6 (Saturday) is false. In JavaScript, for example, the getDate() method of the Date object returns the day of the month, which can range from 1 to 31 depending on the month and year. To get the day of the week, you would use the getDay() method, which indeed returns an integer between 0 (Sunday) and 6 (Saturday). Therefore, in the context of JavaScript's date methods, the correct method to determine the day of the week is getDay(), not getDate().
