What was the date 90 months ago?

Solution

Sunday October 29, 2017

0

90 months before today was 29 Oct 2017, a Sunday. Subtracting 90 months in the past is usually just counting from April; 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 29 days left in the end of April to prep for an additional calculation before March. But that’s all there is to it - understand the month, if 90 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 90 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 90 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 29 Apr, then set the calculation - 90 months, and factored in the year 2025
  2. Noted your current time of year: 90 months in April will bring us back to March or further.
  3. Counted backwards months from current day: date - 29 Apr, factoring in the 29 days left in April to calculate Sunday October 29, 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 October 29

  • Current date: 29 Apr
  • Day of the week: Sunday
  • New Date: Sunday October 29, 2017
  • New Date Day of the week: Sunday
  • October marks the start of Q4 so counting backward will put you back into the 3 fiscal quarter.
  • 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 90 months ago

  1. Calculate it: Start with a time ago calculator. 90 months is easiest solved on a calculator. For ours, we've already factored in the 29 days in April + 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 April's calendar: Begin by identifying 29 Apr on a calendar, note that it’s Sunday, and the total days in March (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 90 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()-90 to get or =WORKDAY(TODAY()), -90, cell:cell) for working months.

Working months in 90 calendar months

90 months is Sunday October 29, 2017 or could be if you only want workdays. This calculation takes 90 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday October 29, 2017 date.
