OK, I assumed you were already doing the math since you mentioned you had a math column.
Can you explain how you come up with 16.23 month? Date math can get a little more tricky when you are trying to calculate Years or Months. Glide’s date math works best with Days. Definitely still doable, but t0 get the right result, we first need to understand your end goal. For example, are you looking for a specific day that’s 16 months from now (Today May 26th 2021 → Goal September 26th 2022), or are you looking for a specific day of the week (the nearest Wednesday in September 2022), or the beginning or end of the month (Sept 1, 2022 or Sept 30, 2022). Mainly the question is, why 16.23 months? What’s the significance of that number?
