What was the date 99 months ago?

Solution

Friday January 13, 2017

Date Range: 99 months

99 months before today was 13 Jan 2017, a Friday. Subtracting 99 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 13 days left in the middle of April to prep for an additional calculation before March. But that’s all there is to it - understand the month, if 99 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 99 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 99 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 13 Apr, then set the calculation - 99 months, and factored in the year 2025
  2. Noted your current time of year: 99 months in April will bring us back to March or further.
  3. Counted backwards months from current day: date - 13 Apr, factoring in the 13 days left in April to calculate Friday January 13, 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 January 13

  • Current date: 13 Apr
  • Day of the week: Friday
  • New Date: Friday January 13, 2017
  • New Date Day of the week: Friday
  • Counting back form January will put you close, if not passed, the previous year.
  • This calculation crosses at least one month. Remeber, this will change our day of the week.
  • The solution crosses into a different year.
  • Your date will be a weekend. Consider if you only want workdays in your calculation.

Ways to calculate 99 months ago

  1. Calculate it: Start with a time ago calculator. 99 months is easiest solved on a calculator. For ours, we've already factored in the 13 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 13 Apr on a calendar, note that it’s Friday, 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 99 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()-99 to get or =WORKDAY(TODAY()), -99, cell:cell) for working months.

Working months in 99 calendar months

99 months is Friday January 13, 2017 or could be if you only want workdays. This calculation takes 99 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Friday January 13, 2017 date.
