210 months before today was 27 Jan 2007, a Saturday. Subtracting 210 months in the past is usually just counting from July; 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 27 days left in the end of July to prep for an additional calculation before June. But that’s all there is to it - understand the month, if 210 months will change the year, season, or fiscal calendar, and subtract your dates.
