What was the date 37 months ago?


Thursday May 20, 2021


37 months before today was 20 May 2021, a Thursday. Subtracting 37 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 20 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 37 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 37 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 37 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 20 Jun, then set the calculation - 37 months, and factored in the year 2024
  2. Noted your current time of year: 37 months in June will bring us back to May or further.
  3. Counted backwards months from current day: date - 20 Jun, factoring in the 20 days left in June to calculate Thursday May 20, 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 May 20

  • Current date: 20 Jun
  • Day of the week: Thursday
  • New Date: Thursday May 20, 2021
  • New Date Day of the week: Thursday
  • Counting backward from May could put you back in Q1 or even the previous year.
  • 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 37 months ago

  1. Calculate it: Start with a time ago calculator. 37 months is easiest solved on a calculator. For ours, we've already factored in the 20 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 20 Jun on a calendar, note that it’s Thursday, 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 37 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()-37 to get or =WORKDAY(TODAY()), -37, cell:cell) for working months.

Working months in 37 calendar months

37 months is Thursday May 20, 2021 or could be if you only want workdays. This calculation takes 37 months and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday May 20, 2021 date.
