In this exercise you'll be working on an appointment scheduler for a beauty salon in New York that opened on September 15th in 2012.

You have four tasks, which will all involve appointment dates. The dates and times will use one of the following three formats:

• "7/25/2019 13:45:00"
• "July 25, 2019 13:45:00"
• "Thursday, July 25, 2019 13:45:00:00"

The tests will automatically set the culture to en-US - you don't have to set or specify the culture yourselves.

1. Parse appointment date

Implement the schedule function that can parse a textual representation of an appointment date into the corresponding DateTime format:

schedule "7/25/2019 13:45:00"
// => DateTime(2019, 7, 25, 13, 45, 0)

2. Check if an appointment has already passed

Implement the hasPassed function that takes an appointment date and checks if the appointment was somewhere in the past:

hasPassed (DateTime(1999, 12, 31, 9, 0, 0))
// => true

3. Check if appointment is in the afternoon

Implement the isAfternoonAppointment function that takes an appointment date and checks if the appointment is in the afternoon (>= 12:00 and < 18:00):

isAfternoonAppointment (DateTime(2019, 03, 29, 15, 0, 0))
// => true

4. Describe the time and date of the appointment

Implement the description function that takes an appointment date and returns a description of that date and time:

description (DateTime(2019, 03, 29, 15, 0, 0))
// => "You have an appointment on Friday 29 March 2019 at 15:00."

5. Return the anniversary date

Implement the anniversaryDate function that returns this year's anniversary date, which is September 15th:

anniversaryDate()
// => DateTime(2019, 9, 15, 0, 0, 0)
