What was the date 138 months ago?


Solution

Friday August 16, 2013

0

138 months before today was 16 Aug 2013, a Friday. Subtracting 138 months in the past is usually just counting from February; 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 16 days left in the middle of February to prep for an additional calculation before January. But that’s all there is to it - understand the month, if 138 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 138 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 138 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 16 Feb, then set the calculation - 138 months, and factored in the year 2025
  2. Noted your current time of year: 138 months in February will bring us back to January or further.
  3. Counted backwards months from current day: date - 16 Feb, factoring in the 16 days left in February to calculate Friday August 16, 2013
  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 August 16

  • Current date: 16 Feb
  • Day of the week: Friday
  • New Date: Friday August 16, 2013
  • New Date Day of the week: Friday
  • August is the beginning of Q3. Dates in previous months will be part of 1H fiscal years.
  • 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 138 months ago

  1. Calculate it: Start with a time ago calculator. 138 months is easiest solved on a calculator. For ours, we've already factored in the 16 days in February + 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 February's calendar: Begin by identifying 16 Feb on a calendar, note that it’s Friday, and the total days in January (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 138 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()-138 to get or =WORKDAY(TODAY()), -138, cell:cell) for working months.

Working months in 138 calendar months

138 months is Friday August 16, 2013 or could be if you only want workdays. This calculation takes 138 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 August 16, 2013 date.
