What was the date 80 years ago?

Solution

Thursday November 23, 1944

0

80 years in the past was 23 Nov 1944, a Thursday. Subtracting 80 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 23 days from the end of November, 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 80 years ago.

How we calculated 80 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 80 years ago gets calculated on each visit:

We started with date inputs: used current day of 23 Nov, then set the calculation - 80 years, and factored in the year 2024
Noted your current time of year: 80 years in November will bring us back to October or further.
Counted backwards years from current day: date - 23 Nov, factoring in the 23 days left in November to calculate Thursday November 23, 1944
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 23

Current date: 23 Nov
Day of the week: Thursday
New Date: Thursday November 23, 1944
New Date Day of the week: Thursday
In Novemeber, account for the end of the year holidays when counting backwards.
The solution crosses into a different year.

Ways to calculate 80 years ago

Calculate it: Start with a time ago calculator. 80 years is easiest solved on a calculator. For ours, we've already factored in the 23 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!).
Use November's calendar: Begin by identifying 23 Nov on a calendar, note that it’s Thursday, 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 80 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()-80 to get or =WORKDAY(TODAY()), -80, cell:cell) for working years.

Working years in 80 calendar years

80 years is Thursday November 23, 1944 or could be if you only want workdays. This calculation takes 80 years and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday November 23, 1944 date.
