Challenge: Calculate Project Deadlines

In project management, you often need to calculate how long a project will take and when key milestones will occur. This task will help you practice date arithmetic by working with project start and end dates, as well as scheduling milestones.

• Calculate the number of days between start_date and end_date.
• For each value in milestone_days, add that many days to start_date to schedule milestone dates.
• Assign the number of days between the project dates to days_between.
• Assign the milestone dates to milestone_schedule.
