What was the date 36 months ago?


Sunday June 13, 2021


36 months before today was 13 Jun 2021, a Sunday. Subtracting 36 months in the past is usually just counting from June; 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 13 days left in the middle of June to prep for an additional calculation before May. But that’s all there is to it - understand the month, if 36 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 36 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 36 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 13 Jun, then set the calculation - 36 months, and factored in the year 2024
  2. Noted your current time of year: 36 months in June will bring us back to May or further.
  3. Counted backwards months from current day: date - 13 Jun, factoring in the 13 days left in June to calculate Sunday June 13, 2021
  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 June 13

  • Current date: 13 Jun
  • Day of the week: Sunday
  • New Date: Sunday June 13, 2021
  • New Date Day of the week: Sunday
  • June is the beginning of summer so be careful, counting backwards could put you in the chilly months of spring and winter.
  • The solution crosses into a different year.

Ways to calculate 36 months ago

  1. Calculate it: Start with a time ago calculator. 36 months is easiest solved on a calculator. For ours, we've already factored in the 13 days in June + 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 June's calendar: Begin by identifying 13 Jun on a calendar, note that it’s Sunday, and the total days in May (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 36 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()-36 to get or =WORKDAY(TODAY()), -36, cell:cell) for working months.

Working months in 36 calendar months

36 months is Sunday June 13, 2021 or could be if you only want workdays. This calculation takes 36 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday June 13, 2021 date.
