51 months before today was 21 Aug 2020, a Friday. Subtracting 51 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 21 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 51 months will change the year, season, or fiscal calendar, and subtract your dates.

51 months is Friday August 21, 2020 or could be if you only want workdays. This calculation takes 51 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Friday August 21, 2020 date.
