To calculate the number of minutes in a week, multiply the number of minutes in an hour by the number of hours in a day, and then by the number of days in a week. There are 60 minutes in an hour, 24 hours in a day, and 7 days in a week. Therefore, there are 1440 minutes in a day (60 minutes/hour * 24 hours/day) and 10,080 minutes in a week (1440 minutes/day * 7 days/week).
