What was the date 20 years ago?

Solution

Monday March 28, 2005

Date Range: 20 years

20 years in the past was 28 Mar 2005, a Monday. Subtracting 20 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 March, 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 20 years ago.

How we calculated 20 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 20 years ago gets calculated on each visit:

  1. We started with date inputs: used current day of 28 Mar, then set the calculation - 20 years, and factored in the year 2025
  2. Noted your current time of year: 20 years in March will keep us in March and we don’t need to worry about adjusting months or years.
  3. Counted backwards years from current day: date - 28 Mar, factoring in the 28 days left in March to calculate Monday March 28, 2005
  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 March 28

  • Current date: 28 Mar
  • Day of the week: Monday
  • New Date: Monday March 28, 2005
  • New Date Day of the week: Monday
  • March is usually not, but sometimes super tricky. Factor in Leap Years and Easter, which falls on varying dates each year, if you need a date in the past.
  • The solution crosses into a different year.

Ways to calculate 20 years ago

  1. Calculate it: Start with a time ago calculator. 20 years is easiest solved on a calculator. For ours, we've already factored in the 28 days in March + 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 March's calendar: Begin by identifying 28 Mar on a calendar, note that it’s Monday, and the total days in February (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 20 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()-20 to get or =WORKDAY(TODAY()), -20, cell:cell) for working years.

Working years in 20 calendar years

20 years is Monday March 28, 2005 or could be if you only want workdays. This calculation takes 20 years and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday March 28, 2005 date.
