140 months before today was 08 Jan 2013, a Tuesday. Subtracting 140 months in the past is usually just counting from September; 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 8 days left in the middle of September to prep for an additional calculation before August. But that’s all there is to it - understand the month, if 140 months will change the year, season, or fiscal calendar, and subtract your dates.

140 months is Tuesday January 08, 2013 or could be if you only want workdays. This calculation takes 140 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Tuesday January 08, 2013 date.
