What was the date 83 months ago?

Solution

Thursday December 21, 2017

0

83 months before today was 21 Dec 2017, a Thursday. Subtracting 83 months in the past is usually just counting from November; 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 21 days left in the end of November to prep for an additional calculation before October. But that’s all there is to it - understand the month, if 83 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 83 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 83 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 21 Nov, then set the calculation - 83 months, and factored in the year 2024
  2. Noted your current time of year: 83 months in November will bring us back to October or further.
  3. Counted backwards months from current day: date - 21 Nov, factoring in the 21 days left in November to calculate Thursday December 21, 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 21

  • Current date: 21 Nov
  • Day of the week: Thursday
  • New Date: Thursday December 21, 2017
  • New Date Day of the week: Thursday
  • 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 83 months ago

  1. Calculate it: Start with a time ago calculator. 83 months is easiest solved on a calculator. For ours, we've already factored in the 21 days in November + 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 November's calendar: Begin by identifying 21 Nov on a calendar, note that it’s Thursday, and the total days in October (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 83 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()-83 to get or =WORKDAY(TODAY()), -83, cell:cell) for working months.

Working months in 83 calendar months

83 months is Thursday December 21, 2017 or could be if you only want workdays. This calculation takes 83 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 December 21, 2017 date.
