Is it a leap year?
In 1582 the Gregorian calendar was introduced. Our planet takes approximately 365.25 days to orbit the sun once. It’s that .25 that creates the need for a leap year every four years. During non-leap years (common years) the calendar doesn’t take into account the extra quarter of a day required by Earth to complete a single orbit. In leap years there are 29 days in February instead of 28.

Make
Write a program to say whether the year entered by a user is a leap year or not. Any year exactly divisible by four is usually a leap year unless it is also divisible by one hundred. The exception is that all years divisible by four hundred are always leap years.
Success Criteria
Remember to add a comment before a subprogram, selection or iteration statement to explain its purpose.
Complete the subprogram called is_leap_year that:
- Returns True if the year is a leap year or False if it is not.
- If the year is exactly divisible by four it is a leap year…
- …unless it is divisible by one hundred in which case it is not a leap year…
- …although any year that is divisible by four hundred is a leap year.
Complete the main program so that:
- The user can input a year.
- It outputs whether the year is a leap year or not.
Typical inputs and outputs from the program would be:
Enter a year: 1900
1900 is not a leap year.
Enter a year: 2000
2000 is a leap year.
Enter a year: 2022
2022 is not a leap year.
Enter a year: 2024
2024 is a leap year.
