770 months before today was 26 Sep 1960, a Monday. Subtracting 770 months in the past is usually just counting from November; 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 26 days left in the end of November to prep for an additional calculation before October. But that’s all there is to it - understand the month, if 770 months will change the year, season, or fiscal calendar, and subtract your dates.

770 months is Monday September 26, 1960 or could be if you only want workdays. This calculation takes 770 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday September 26, 1960 date.
