980 months before today was 15 Jul 1943, a Thursday. Subtracting 980 months in the past is usually just counting from March; 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 15 days left in the middle of March to prep for an additional calculation before February. But that’s all there is to it - understand the month, if 980 months will change the year, season, or fiscal calendar, and subtract your dates.
