What was the date 21 months ago?

Solution

Friday August 19, 2022

0

21 months before today was 19 Aug 2022, a Friday. Subtracting 21 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 19 days left in the middle of May to prep for an additional calculation before April. But that’s all there is to it - understand the month, if 21 months will change the year, season, or fiscal calendar, and subtract your dates.

How we calculated 21 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 21 months ago gets calculated on each visit:

  1. We started with date inputs: used current day of 19 May, then set the calculation - 21 months, and factored in the year 2024
  2. Noted your current time of year: 21 months in May will bring us back to April or further.
  3. Counted backwards months from current day: date - 19 May, factoring in the 19 days left in May to calculate Friday August 19, 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 August 19

  • Current date: 19 May
  • Day of the week: Friday
  • New Date: Friday August 19, 2022
  • New Date Day of the week: Friday
  • August is the beginning of Q3. Dates in previous months will be part of 1H fiscal years.
  • 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 21 months ago

  1. Calculate it: Start with a time ago calculator. 21 months is easiest solved on a calculator. For ours, we've already factored in the 19 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 19 May on a calendar, note that it’s Friday, 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 21 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()-21 to get or =WORKDAY(TODAY()), -21, cell:cell) for working months.

Working months in 21 calendar months

21 months is Friday August 19, 2022 or could be if you only want workdays. This calculation takes 21 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 August 19, 2022 date.
