Sorry trex, we can't handle your insurance claim
Just having fun with Elixir and seeing this method.
thinking would months in a year ever change.. but then seeing the error playing around 
iex(1)> Calendar.ISO.months_in_year(1)
12
iex(2)> Calendar.ISO.months_in_year(99)
12
iex(3)> Calendar.ISO.months_in_year(3939848447)
** (FunctionClauseError) no function clause matching in Calendar.ISO.months_in_year/1
The following arguments were given to Calendar.ISO.months_in_year/1:
# 1
3939848447
Attempted function clauses (showing 1 out of 1):
def months_in_year(year) when is_integer(year) and (year >= -9999 and year <= 9999)
(elixir 1.11.3) lib/calendar/iso.ex:601: Calendar.ISO.months_in_year/1

This is as sepcified in ISO 8601. Extended years with more than 4 digits are not mandatory and require prior agreement with sender and receiver of the date.
In theory implementing an own Calendar.ExtendedISO which supports years with more than 4 digits should be possible and would fullfil the “prior agreement” part.
