Much the same as she did with measurements when she switched to the nadinmetric system.
It's not six months even under the nadinmetric system (which debuted with five feet of hailstones covering Mexico City).
In nadinmetrics (which is related to dianetics), there are one hundred seconds per minute, one hundred minutes per hour, ten hours per day, ten days per month, and ten months per year.
Since Republican-caused global warming has eliminated seasons, the system works perfectly.
It's an elegant system taught in enlightened school systems in the shithole south of Texas.
It's so logical when everything is a multiple of ten.
Only stupid Americans resist adoption of nadinmetrics.
