What was the date 79 years ago?


Friday June 15, 1945


79 years in the past was 15 Jun 1945, a Friday. Subtracting 79 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 15 days from the end of June, 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 79 years ago.

How we calculated 79 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 79 years ago gets calculated on each visit:

  1. We started with date inputs: used current day of 15 Jun, then set the calculation - 79 years, and factored in the year 2024
  2. Noted your current time of year: 79 years in June will bring us back to May or further.
  3. Counted backwards years from current day: date - 15 Jun, factoring in the 15 days left in June to calculate Friday June 15, 1945
  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 June 15

  • Current date: 15 Jun
  • Day of the week: Friday
  • New Date: Friday June 15, 1945
  • New Date Day of the week: Friday
  • June is the beginning of summer so be careful, counting backwards could put you in the chilly months of spring and winter.
  • 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 79 years ago

  1. Calculate it: Start with a time ago calculator. 79 years is easiest solved on a calculator. For ours, we've already factored in the 15 days in June + 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 June's calendar: Begin by identifying 15 Jun on a calendar, note that it’s Friday, and the total days in May (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 79 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()-79 to get or =WORKDAY(TODAY()), -79, cell:cell) for working years.

Working years in 79 calendar years

79 years is Friday June 15, 1945 or could be if you only want workdays. This calculation takes 79 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 June 15, 1945 date.
