What was the date 109 months ago?

Solution

Saturday December 05, 2015

0

109 months before today was 05 Dec 2015, a Saturday. Subtracting 109 months in the past is usually just counting from January; 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 5 days left in the early part of January to prep for an additional calculation before . But that’s all there is to it - understand the month, if 109 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 109 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 109 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 05 Jan, then set the calculation - 109 months, and factored in the year 2025
  2. Noted your current time of year: 109 months in January will bring us back to or further.
  3. Counted backwards months from current day: date - 05 Jan, factoring in the 5 days left in January to calculate Saturday December 05, 2015
  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 05

  • Current date: 05 Jan
  • Day of the week: Saturday
  • New Date: Saturday December 05, 2015
  • New Date Day of the week: Saturday
  • 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.
  • Your date will be a weekend. Consider if you only want workdays in your calculation.

Ways to calculate 109 months ago

  1. Calculate it: Start with a time ago calculator. 109 months is easiest solved on a calculator. For ours, we've already factored in the 5 days in January + 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 January's calendar: Begin by identifying 05 Jan on a calendar, note that it’s Saturday, and the total days in (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 109 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()-109 to get or =WORKDAY(TODAY()), -109, cell:cell) for working months.

Working months in 109 calendar months

109 months is Saturday December 05, 2015 or could be if you only want workdays. This calculation takes 109 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Saturday December 05, 2015 date.
