What was the date 99 months ago?

Solution

Wednesday December 07, 2016

Date Range: 99 months

99 months before today was 07 Dec 2016, a Wednesday. Subtracting 99 months in the past is usually just counting from March; 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 7 days left in the early part of March to prep for an additional calculation before February. 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 07 Mar, then set the calculation - 99 months, and factored in the year 2025
  2. Noted your current time of year: 99 months in March will bring us back to February or further.
  3. Counted backwards months from current day: date - 07 Mar, factoring in the 7 days left in March to calculate Wednesday December 07, 2016
  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 07

  • Current date: 07 Mar
  • Day of the week: Wednesday
  • New Date: Wednesday December 07, 2016
  • 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 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 7 days in March + 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 March's calendar: Begin by identifying 07 Mar on a calendar, note that it’s Wednesday, and the total days in February (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 Wednesday December 07, 2016 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 Wednesday December 07, 2016 date.
