date = .datetime~new(2008, 12, 25)

lastdate = .datetime~new(2121, 12, 25)

resultList = .array~new -- our collector of years

-- date objects are directly comparable

loop while date <= lastdate

if date~weekday == 7 then resultList~append(date~year)

-- step to the next year

date = date~addYears(1)
