How to define irregular service in GTFS

Does anyone know how I should define a transit service that only occurs on public holidays, in GTFS? 

calendar.txt as;
'4,0,0,0,0,0,0,0,20161211,20171209'

calendar_dates.txt as;
'4,20171001,1'
'4,20171002,1'
'4,20171225,1'
'4,20171226,1'

This apparently does not seem to work... My dataset also contains normal regular services, and they work fine.

You need to both add new service and cancel the service

In this case, New Year’s Day is added as a Sunday schedule (exception_type 1), with the existing weekday schedule cancelled out (exception_type 2). In calendar.txt:

service_id,monday,tuesday,wednesday,thursday,friday,saturday,sunday,start_date,end_date
weekday,1,1,1,1,1,0,0,20140101,20240101
saturday,0,0,0,0,0,1,0,20140101,20240101
sunday,0,0,0,0,0,0,1,20140101,20240101

In calendar_dates.txt:

service_id,date,exception_type
weekday,20140101,2
Sunday,20140101,1

See my blog post : http://transitdata.net/on-calendars-and-calendar_dates/ for more info

Populate calendar_dates.txt exactly as you have shown above and put nothing in calendar.txt for service id 4

This is permitted by the spec, see

https://developers.google.com/transit/gtfs/reference/#calendar_datestxt

and I suspect that inserting an entry into calendar.txt with none of the days set to 1 is confusing validators.
