I used a slightly different approach ­ below is a snippet of my [day-menu]
context that I did for one of my installs. I load up the site's holiday
schedule in the Asterisk data base (I do it once per year, and train someone
to do it if I cannot), then check for the current date/holiday key ­ if it
is =1 then I play out the holiday greetings, otherwise I play out the day or
night greeting. The second argument to STRFTIME is the time zone ­ be sure
to get that right for your installation.
[day-menu]
exten => s,1,Answer()
exten => s,n,Wait(1.5) ; Wait for callerID spill

exten => s,n,Set(DATE=${STRFTIME(${EPOCH},ChST,%C%y%m%d)})
exten => s,n,Verbose(2,---> Current date is ${DATE})

exten => s,n(reinit),Set(COUNTER=0)
exten => s,n,GotoIf($["${DB(custom/${DATE}/holiday)}" = "1"]?holiday)
exten => s,n,Goto(daycheck)
exten => s,n(holiday),Set(MENU=holiday-menu)
exten => s,n,Goto(playmenu)
exten => s,n(daycheck),GotoIfTime(08:00-16:59,mon-fri,*,*?open)
exten => s,n,Set(MENU=night-menu)
exten => s,n,Goto(night)
exten => s,n(open),Set(MENU=day-menu)
exten => s,n(night),NoOp()
exten => s,n(top),Wait(0.5)
exten => s,n,GotoIf($[${COUNTER}>=10]?wrong)
exten => s,n(playmenu),Background(${MENU})
exten => s,n(bypass),WaitExten(10)
; go straight to VM if they time out...
exten => s,n,Goto(2,1)
exten => s,n(wrong),Playback(something-terribly-wrong)
exten => s,n,Playback(goodbye)
exten => s,n,Hangup()

Hopefully this is enough to get you started.
