#LEAP YEAR RULES#
# Leap year falls on every year that is evenly divisible by 4 
# **except** every year that is evenly divisible by 100 
# **unless** the year is also evenly divisible by 400

#Collect year query
year = int(input("Which year do you want to check? "))
#calculate based on Leap year rules, using nested if statements
