What was the date 140 months ago?


Thursday September 27, 2012


140 months before today was 27 Sep 2012, a Thursday. Subtracting 140 months in the past is usually just counting from May; however, longer calculations will push us from 2024 into 2023 or further. Even if the calculation remains within the year, I usually take note of the 27 days left in the end of May to prep for an additional calculation before April. But that’s all there is to it - understand the month, if 140 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 140 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 140 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 27 May, then set the calculation - 140 months, and factored in the year 2024
  2. Noted your current time of year: 140 months in May will bring us back to April or further.
  3. Counted backwards months from current day: date - 27 May, factoring in the 27 days left in May to calculate Thursday September 27, 2012
  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 September 27

  • Current date: 27 May
  • Day of the week: Thursday
  • New Date: Thursday September 27, 2012
  • New Date Day of the week: Thursday
  • Counting backward from September puts you back into the summer! September is the official start of fall.
  • 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 140 months ago

  1. Calculate it: Start with a time ago calculator. 140 months is easiest solved on a calculator. For ours, we've already factored in the 27 days in May + 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 May's calendar: Begin by identifying 27 May on a calendar, note that it’s Thursday, and the total days in April (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 140 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()-140 to get or =WORKDAY(TODAY()), -140, cell:cell) for working months.

Working months in 140 calendar months

140 months is Thursday September 27, 2012 or could be if you only want workdays. This calculation takes 140 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday September 27, 2012 date.
