990 months before today was 26 Aug 1942, a Wednesday. Subtracting 990 months in the past is usually just counting from February; however, longer calculations will push us from 2025 into 2024 or further. Even if the calculation remains within the year, I usually take note of the 26 days left in the end of February to prep for an additional calculation before January. But that’s all there is to it - understand the month, if 990 months will change the year, season, or fiscal calendar, and subtract your dates.
