What was the date 21 months ago?

Solution

Friday April 28, 2023

0

21 months before today was 28 Apr 2023, a Friday. Subtracting 21 months in the past is usually just counting from January; 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 28 days left in the end of January to prep for an additional calculation before . 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 28 Jan, then set the calculation - 21 months, and factored in the year 2025
  2. Noted your current time of year: 21 months in January will keep us in January and we don’t need to worry about adjusting months or years.
  3. Counted backwards months from current day: date - 28 Jan, factoring in the 28 days left in January to calculate Friday April 28, 2023
  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 April 28

  • Current date: 28 Jan
  • Day of the week: Friday
  • New Date: Friday April 28, 2023
  • New Date Day of the week: Friday
  • April is the end of the quarter and the beginning of spring. It's also Phillies Opening Day, so plan according and take the week off work! (Go Phils)
  • 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 28 days in January + 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 January's calendar: Begin by identifying 28 Jan on a calendar, note that it’s Friday, and the total days in (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 April 28, 2023 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 April 28, 2023 date.
