What was the date 155 months ago?

Solution

Saturday December 24, 2011

0

155 months before today was 24 Dec 2011, a Saturday. Subtracting 155 months in the past is usually just counting from November; 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 24 days left in the end of November to prep for an additional calculation before October. But that’s all there is to it - understand the month, if 155 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 155 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 155 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 24 Nov, then set the calculation - 155 months, and factored in the year 2024
  2. Noted your current time of year: 155 months in November will bring us back to October or further.
  3. Counted backwards months from current day: date - 24 Nov, factoring in the 24 days left in November to calculate Saturday December 24, 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 December 24

  • Current date: 24 Nov
  • Day of the week: Saturday
  • New Date: Saturday December 24, 2011
  • 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 155 months ago

  1. Calculate it: Start with a time ago calculator. 155 months is easiest solved on a calculator. For ours, we've already factored in the 24 days in November + 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 November's calendar: Begin by identifying 24 Nov on a calendar, note that it’s Saturday, and the total days in October (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 155 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()-155 to get or =WORKDAY(TODAY()), -155, cell:cell) for working months.

Working months in 155 calendar months

155 months is Saturday December 24, 2011 or could be if you only want workdays. This calculation takes 155 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 24, 2011 date.
