Thanks @aulemahal—sorry for taking so long to take a look at this. The tests / implementation look reasonable.

whats-new.rstSmall PR to add a new "method" to convert to and from 360_day calendars. The current two methods (chosen with the
align_onkeyword) will always remove or add the same day-of-year for all years of the same length.This new option will randomly chose the days, one for each fifth of the year (72-days period). It emulates the method of the LOCA datasets (see web page and article ). February 29th is always removed/added when the source/target is a leap year.
I copied the implementation from xclim (which I wrote), see code here .
