What was the date 21 years ago?


Wednesday May 28, 2003


21 years in the past was 28 May 2003, a Wednesday. Subtracting 21 years in the past is usually simple. Anything under a decade can usually be counted on one hand. The biggest challenge will be skipping decades behind or even centuries. Additionally, we’re 28 days from the end of May, so being in the end of of the month, you'll need to consider monthly changes as well. Weekly and daily changes most likely won't impact 21 years ago.

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

  1. We started with date inputs: used current day of 28 May, then set the calculation - 21 years, and factored in the year 2024
  2. Noted your current time of year: 21 years in May will keep us in May and we don’t need to worry about adjusting months or years.
  3. Counted backwards years from current day: date - 28 May, factoring in the 28 days left in May to calculate Wednesday May 28, 2003
  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 28

  • Current date: 28 May
  • Day of the week: Wednesday
  • New Date: Wednesday May 28, 2003
  • New Date Day of the week: Wednesday
  • Counting backward from May could put you back in Q1 or even the previous year.
  • The solution crosses into a different year.

Ways to calculate 21 years ago

  1. Calculate it: Start with a time ago calculator. 21 years is easiest solved on a calculator. For ours, we've already factored in the 28 days in May + all number of days in each month and the number of days in . Simply add your years 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 28 May on a calendar, note that it’s Wednesday, 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 years by years, subtracting years from until your remainder of years is 0.
  3. Use excel: For more complex years 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 years.

Working years in 21 calendar years

21 years is Wednesday May 28, 2003 or could be if you only want workdays. This calculation takes 21 years and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Wednesday May 28, 2003 date.
