0

4 years in the past was 13 Nov 2020, a Friday. Subtracting 4 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 13 days from the end of November, 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 4 years ago.

How we calculated 4 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 4 years ago gets calculated on each visit:

  1. We started with date inputs: used current day of 13 Nov, then set the calculation - 4 years, and factored in the year 2024
  2. Noted your current time of year: 4 years in November will keep us in November and we don’t need to worry about adjusting months or years.
  3. Counted backwards years from current day: date - 13 Nov, factoring in the 13 days left in November to calculate Friday November 13, 2020
  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 November 13

  • Current date: 13 Nov
  • Day of the week: Friday
  • New Date: Friday November 13, 2020
  • New Date Day of the week: Friday
  • In Novemeber, account for the end of the year holidays when counting backwards.
  • 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 4 years ago

  1. Calculate it: Start with a time ago calculator. 4 years is easiest solved on a calculator. For ours, we've already factored in the 13 days in November + 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 November's calendar: Begin by identifying 13 Nov on a calendar, note that it’s Friday, and the total days in October (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 4 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()-4 to get or =WORKDAY(TODAY()), -4, cell:cell) for working years.

Working years in 4 calendar years

4 years is Friday November 13, 2020 or could be if you only want workdays. This calculation takes 4 years and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Friday November 13, 2020 date.
