Year period calculation

should we consider december as the last month
of the business year period
or use january as the last month
considering the geopolitical event that has happened ?

What geopolitical event?

My business year ends April as that is when the tax year starts and ends. No other month.

ok that is an other pov

December’s not really a full month but I think we have to treat it as Month 12 because so many big players do so, its the end of the year and the end of a financial quarter.

thanx tom for your pov
the reason i am asking is because i want to build my fractal for year 2020
and need a 12 month business period
so i was undecided between using the usual normal calendar or look for a major milestone event like the war with iran and use it as the beginning of 2020 business period and the end of 2019 business year

Not a bad idea to allow for anomalous events like that. What about a sort of rolling calendar? - so that whatever the current month its always Month 12 AND Month 1?

that is an excellent input
need to test it with past years to see the outcome
thanks
