Syntax error?

[enderfran2006]

Hello I am trying to make a calender on Python but for some reason it is not working. could some one help

event = int(input("When is your event?")

    if event == 1:
            first = input("What is happening that day?")
            print("So on the 1st of January it is",first,)
    

    if event == 2:
           second = input("What is happening that day?")
           print("So on the 2nd of January it is",second,)

    if event == 3:
           third = input("What is happening that day?")
           print("So on the 3rd of January it is",third,)

The error says its something to do with the : in if event== 1
