My if statement is not returning what I think it should return

Question

def daysOfMonth():

    month = input('Input the name of Month: ') 

    if month == 'January' or 'March' or 'May' or 'July' or 'August' or 'October' or 'December ':
      print('No. of days: 31 days')

    elif month == 'February':
      print('No. of days: 28 days')

    elif month == 'April' or "June" or 'September' or 'November':
      print('No. of days: 30 days')
    

I Input April and it says 31 days
