Ruby CSV enumeration confusion - ruby

Question

How come this does not work? The CSV is there and has values, and I have 'require "csv" and time at the top, so good there. The problem seems to be with csv.each actually doing anything.
It returns
=> [] is the most common registration hour
=> [] is the most common registration day (Sunday being 0, Mon => 1 ... Sat => 7)
If there is any more info I can provide, please let me know.
#x = CSV.open \
'event_attendees.csv', headers: true, header_converters: :symbol
def time_target
y = []
#x.each do |line|
if line[:regdate].to_s.length > 0
y << DateTime.strptime(line[:regdate], "%m/%d/%y %H:%M").hour
y = y.sort_by {|i| grep(i).length }.last
end
end
puts "#{y} is the most common registration hour"
y = []
#x.each do |line|
if line[:regdate].to_s.length > 0
y << DateTime.strptime(line[:regdate], "%m/%d/%y %H:%M").wday
y = y.sort_by {|i| grep(i).length }.last
end
end
puts "#{y} is the most common registration day \
(Sunday being 0, Mon => 1 ... Sat => 7)"
end
making all the 'y's '#y's has not fixed it.
Here is sample from the CSV I'm using:
,RegDate,first_Name,last_Name,Email_Address,HomePhone,Street,City,State,Zipcode

Try this to load your data:
def database_load(arg='event_attendees.csv')
#contents = CSV.open(arg, headers: true, header_converters: :symbol)
#people = []
#contents.each do |row|
person = {}
person["id"] = row[0]
person["regdate"] = row[:regdate]
person["first_name"] = row[:first_name].downcase.capitalize
person["last_name"] = row[:last_name].downcase.capitalize
person["email_address"] = row[:email_address]
person["homephone"] = PhoneNumber.new(row[:homephone].to_s)
person["street"] = row[:street]
person["city"] = City.new(row[:city]).clean
person["state"] = row[:state]
person["zipcode"] = Zipcode.new(row[:zipcode]).clean
#people << person
end
puts "Loaded #{#people.count} Records from file: '#{arg}'..."
end
