What was the date 40 months ago?

Solution

Tuesday March 15, 2022

0

40 months before today was 15 Mar 2022, a Tuesday. Subtracting 40 months in the past is usually just counting from July; however, longer calculations will push us from 2025 into 2024 or further. Even if the calculation remains within the year, I usually take note of the 15 days left in the middle of July to prep for an additional calculation before June. But that’s all there is to it - understand the month, if 40 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 40 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 40 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 15 Jul, then set the calculation - 40 months, and factored in the year 2025
  2. Noted your current time of year: 40 months in July will bring us back to June or further.
  3. Counted backwards months from current day: date - 15 Jul, factoring in the 15 days left in July to calculate Tuesday March 15, 2022
  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 March 15

  • Current date: 15 Jul
  • Day of the week: Tuesday
  • New Date: Tuesday March 15, 2022
  • New Date Day of the week: Tuesday
  • March is usually not, but sometimes super tricky. Factor in Leap Years and Easter, which falls on varying dates each year, if you need a date in the past.
  • 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 40 months ago

  1. Calculate it: Start with a time ago calculator. 40 months is easiest solved on a calculator. For ours, we've already factored in the 15 days in July + 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 July's calendar: Begin by identifying 15 Jul on a calendar, note that it’s Tuesday, and the total days in June (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 40 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()-40 to get or =WORKDAY(TODAY()), -40, cell:cell) for working months.

Working months in 40 calendar months

40 months is Tuesday March 15, 2022 or could be if you only want workdays. This calculation takes 40 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Tuesday March 15, 2022 date.
