[asterisk-users] asterisk go to "holiday" extension but hoiday is not defined

[Joseph]

When a call comes in asterisk is forwarding the call to holiday extension, even though the holiday is not defined.

Here is my dial plan

exten => 4,1,GotoIfTime(*,*,1,jan?holiday,s,1)  ; new years day
exten => 4,n,GotoIfTime(*,*,6,apr?holiday,s,1) ; easter holiday
exten => 4,n,GotoIfTime(*,*,23,may?holiday,s,1)
exten => 4,n,GotoIfTime(*,*,1,|jul?holiday,s,1)  ; canada day
exten => 4,n,GotoIfTime(*,*,1,aug?holiday,s,1)  ; long weekend
...

Today is May 1, so why is it going to "holiday" extension?
Is there another dial plan that holidays are defined? 
I'm using asterisk 1.8.10
