Don Park 3:15pm feeling tricky by listing all hours in a day with this ruby:

["am","pm"].map{|m| (["12"]+1.upto(11).to_a).map{|h| "#{h} #{m}"}}.flatten

RobotAdam 2:53pm @donpdonp That's fun. A Python variation:

itertools.chain(*(("%d %s" % (h, t) for h in [12] + range(1, 12)) for t in ('am', 'pm'))) 
 

@selenamarie 3:10pm @donpdonp @robotadam hmmm…

for my $meridiem (qw/am pm/) { print map { $_ . $meridiem . ' '} (12,1..11); }
12am 1am 2am 3am 4am 5am 6am 7am 8am 9am 10am 11am 12pm 1pm 2pm 3pm 4pm 5pm 6pm 7pm 8pm 9pm 10pm 11pm

@MarkusQ 4:22pm: @donpdonp If you'd like to feel even trickier:

(0..23).map { |h| "#{((h-1) % 12)+1} #{%w{A P}[h/12]}M" }  
=> ["12 AM", "1 AM", "2 AM", "3 AM", "4 AM", "5 AM", "6 AM", "7 AM", "8 AM", "9 AM", "10 AM", "11 AM", "12 PM", "1 PM", "2 PM", "3 PM", "4 PM", "5 PM", "6 PM", "7 PM", "8 PM", "9 PM", "10 PM", "11 PM"]
