120 months before today was 27 Jul 2014, a Sunday. Subtracting 120 months in the past is usually just counting from July; 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 27 days left in the end of July to prep for an additional calculation before June. But that’s all there is to it - understand the month, if 120 months will change the year, season, or fiscal calendar, and subtract your dates.

120 months is Sunday July 27, 2014 or could be if you only want workdays. This calculation takes 120 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday July 27, 2014 date.
