What was the date 150 months ago?


Saturday November 26, 2011


150 months before today was 26 Nov 2011, a Saturday. Subtracting 150 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 26 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 150 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 150 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 150 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 26 May, then set the calculation - 150 months, and factored in the year 2024
  2. Noted your current time of year: 150 months in May will bring us back to April or further.
  3. Counted backwards months from current day: date - 26 May, factoring in the 26 days left in May to calculate Saturday November 26, 2011
  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 26

  • Current date: 26 May
  • Day of the week: Saturday
  • New Date: Saturday November 26, 2011
  • New Date Day of the week: Saturday
  • 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.
  • Your date will be a weekend. Consider if you only want workdays in your calculation.

Ways to calculate 150 months ago

  1. Calculate it: Start with a time ago calculator. 150 months is easiest solved on a calculator. For ours, we've already factored in the 26 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 26 May on a calendar, note that it’s Saturday, 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 150 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()-150 to get or =WORKDAY(TODAY()), -150, cell:cell) for working months.

Working months in 150 calendar months

150 months is Saturday November 26, 2011 or could be if you only want workdays. This calculation takes 150 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 November 26, 2011 date.
