160 months before today was 22 Jul 2011, a Friday. Subtracting 160 months in the past is usually just counting from November; however, longer calculations will push us from 2024 into 2023 or further. Even if the calculation remains within the year, I usually take note of the 22 days left in the end of November to prep for an additional calculation before October. But that’s all there is to it - understand the month, if 160 months will change the year, season, or fiscal calendar, and subtract your dates.
