221 months before today was 04 Dec 2005, a Sunday. Subtracting 221 months in the past is usually just counting from May; 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 4 days left in the early part of May to prep for an additional calculation before April. But that’s all there is to it - understand the month, if 221 months will change the year, season, or fiscal calendar, and subtract your dates.
