What was the date 138 months ago?

Solution

Sunday November 04, 2012

0

138 months before today was 04 Nov 2012, a Sunday. Subtracting 138 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 4 days left in the early part of May to prep for an additional calculation before April. 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 04 May, then set the calculation - 138 months, and factored in the year 2024
  2. Noted your current time of year: 138 months in May will bring us back to April or further.
  3. Counted backwards months from current day: date - 04 May, factoring in the 4 days left in May to calculate Sunday November 04, 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 November 04

  • Current date: 04 May
  • Day of the week: Sunday
  • New Date: Sunday November 04, 2012
  • New Date Day of the week: Sunday
  • In Novemeber, account for the end of the year holidays 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 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 4 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 04 May on a calendar, note that it’s Sunday, 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 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 Sunday November 04, 2012 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 Sunday November 04, 2012 date.
