What was the date 78 months ago?


Saturday November 25, 2017


78 months before today was 25 Nov 2017, a Saturday. Subtracting 78 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 25 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 78 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 78 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 78 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 25 May, then set the calculation - 78 months, and factored in the year 2024
  2. Noted your current time of year: 78 months in May will bring us back to April or further.
  3. Counted backwards months from current day: date - 25 May, factoring in the 25 days left in May to calculate Saturday November 25, 2017
  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 25

  • Current date: 25 May
  • Day of the week: Saturday
  • New Date: Saturday November 25, 2017
  • 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 78 months ago

  1. Calculate it: Start with a time ago calculator. 78 months is easiest solved on a calculator. For ours, we've already factored in the 25 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 25 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 78 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()-78 to get or =WORKDAY(TODAY()), -78, cell:cell) for working months.

Working months in 78 calendar months

78 months is Saturday November 25, 2017 or could be if you only want workdays. This calculation takes 78 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 25, 2017 date.
