What was the date 21 years ago?

Solution

Sunday May 18, 2003

0

21 years in the past was 18 May 2003, a Sunday. 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 18 days from the end of May, so being in the middle 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:

We started with date inputs: used current day of 18 May, then set the calculation - 21 years, and factored in the year 2024
Noted your current time of year: 21 years in May will bring us back to April or further.
Counted backwards years from current day: date - 18 May, factoring in the 18 days left in May to calculate Sunday May 18, 2003
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 18

Current date: 18 May
Day of the week: Sunday
New Date: Sunday May 18, 2003
New Date Day of the week: Sunday
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

Calculate it: Start with a time ago calculator. 21 years is easiest solved on a calculator. For ours, we've already factored in the 18 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!).
Use May's calendar: Begin by identifying 18 May on a calendar, note that it’s Sunday, 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.
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 Sunday May 18, 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 Sunday May 18, 2003 date.
