What was the date 91 months ago?

Solution

Wednesday December 20, 2017

0

91 months before today was 20 Dec 2017, a Wednesday. Subtracting 91 months in the past is usually just counting from July; however, longer calculations will push us from 2025 into 2024 or further. Even if the calculation remains within the year, I usually take note of the 20 days left in the middle of July to prep for an additional calculation before June. But that’s all there is to it - understand the month, if 91 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 91 months before today

All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 91 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 20 Jul, then set the calculation - 91 months, and factored in the year 2025
  2. Noted your current time of year: 91 months in July will bring us back to June or further.
  3. Counted backwards months from current day: date - 20 Jul, factoring in the 20 days left in July to calculate Wednesday December 20, 2017
  4. Did NOT factor in workdays: In this calculation, we kept weekend. See below for just workdays or the fiscal calendar

Tips when solving for December 20

  • Current date: 20 Jul
  • Day of the week: Wednesday
  • New Date: Wednesday December 20, 2017
  • New Date Day of the week: Wednesday
  • December marks the end of the year, so account for all the out of office notifications when counting backwards.
  • This calculation crosses at least one month. Remeber, this will change our day of the week.
  • The solution crosses into a different year.

Ways to calculate 91 months ago

  1. Calculate it: Start with a time ago calculator. 91 months is easiest solved on a calculator. For ours, we've already factored in the 20 days in July + all number of days in each month and the number of days in . Simply add your months and choose the length of time, then click "calculate". This calculation does not factor in workdays or holidays (see below!).
  2. Use July's calendar: Begin by identifying 20 Jul on a calendar, note that it’s Wednesday, and the total days in June (trust me, you’ll need this for smaller calculations) and days until last year (double trust me, you'll need this for larger calculations). From there, count backwards 91 times months by months, subtracting months from until your remainder of months is 0.
  3. Use excel: For more complex months calculations or if you h8 our site (kidding), I use Excel functions like =TODAY()-91 to get or =WORKDAY(TODAY()), -91, cell:cell) for working months.

Working months in 91 calendar months

91 months is Wednesday December 20, 2017 or could be if you only want workdays. This calculation takes 91 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Wednesday December 20, 2017 date.
