39 months before today was 25 Jan 2021, a Monday. Subtracting 39 months in the past is usually just counting from April; 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 5 days left in the end of April to prep for an additional calculation before 2024-04-25 15:43:38.034727. But that’s all there is to it - understand the month, if 39 months will change the year, season, or fiscal calendar, and subtract your dates.

39 months is Monday January 25, 2021 or could be if you only want workdays. This calculation takes 39 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 January 25, 2021 date.
