What was the date 171 months ago?

Solution

Friday July 23, 2010

0

171 months before today was 23 Jul 2010, a Friday. Subtracting 171 months in the past is usually just counting from October; 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 23 days left in the end of October to prep for an additional calculation before September. But that’s all there is to it - understand the month, if 171 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 171 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 171 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 23 Oct, then set the calculation - 171 months, and factored in the year 2024
  2. Noted your current time of year: 171 months in October will bring us back to September or further.
  3. Counted backwards months from current day: date - 23 Oct, factoring in the 23 days left in October to calculate Friday July 23, 2010
  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 July 23

  • Current date: 23 Oct
  • Day of the week: Friday
  • New Date: Friday July 23, 2010
  • New Date Day of the week: Friday
  • July is one of the highest vacation months, so prepare for more OOO messages.
  • 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 171 months ago

  1. Calculate it: Start with a time ago calculator. 171 months is easiest solved on a calculator. For ours, we've already factored in the 23 days in October + 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 October's calendar: Begin by identifying 23 Oct on a calendar, note that it’s Friday, and the total days in September (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 171 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()-171 to get or =WORKDAY(TODAY()), -171, cell:cell) for working months.

Working months in 171 calendar months

171 months is Friday July 23, 2010 or could be if you only want workdays. This calculation takes 171 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 July 23, 2010 date.
