86 months before today was 22 Dec 2017, a Friday. Subtracting 86 months in the past is usually just counting from February; however, longer calculations will push us from 2025 into 2024 or further.

But that’s all there is to it - understand the month, if 86 months will change the year, season, or fiscal calendar, and subtract your dates.
