54 months before today was 02 Dec 2019, a Monday. Subtracting 54 months in the past is usually just counting from June; 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 2 days left in the early part of June to prep for an additional calculation before May. But that’s all there is to it - understand the month, if 54 months will change the year, season, or fiscal calendar, and subtract your dates.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 54 months ago gets calculated on each visit:
54 months is Monday December 02, 2019 or could be if you only want workdays. This calculation takes 54 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 December 02, 2019 date.
