240 months before today was 07 Oct 2004, a Thursday. Subtracting 240 months in the past is usually just counting from October; 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 7 days left in the early part of October to prep for an additional calculation before September. But that’s all there is to it - understand the month, if 240 months will change the year, season, or fiscal calendar, and subtract your dates.

240 months is Thursday October 07, 2004 or could be if you only want workdays. This calculation takes 240 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday October 07, 2004 date.
