13 months before today was 11 Apr 2023, a Tuesday. Subtracting 13 months in the past is usually just counting from May; 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 11 days left in the middle of May to prep for an additional calculation before April. But that’s all there is to it - understand the month, if 13 months will change the year, season, or fiscal calendar, and subtract your dates.

13 months is Tuesday April 11, 2023 or could be if you only want workdays. This calculation takes 13 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 April 11, 2023 date.
