What was the date 42 years ago?

Solution

Monday July 18, 1983

0

42 years in the past was 18 Jul 1983, a Monday. Subtracting 42 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 July, 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 42 years ago.

How we calculated 42 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 42 years ago gets calculated on each visit:

  1. We started with date inputs: used current day of 18 Jul, then set the calculation - 42 years, and factored in the year 2025
  2. Noted your current time of year: 42 years in July will bring us back to June or further.
  3. Counted backwards years from current day: date - 18 Jul, factoring in the 18 days left in July to calculate Monday July 18, 1983
  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 July 18

  • Current date: 18 Jul
  • Day of the week: Monday
  • New Date: Monday July 18, 1983
  • New Date Day of the week: Monday
  • July is one of the highest vacation months, so prepare for more OOO messages.
  • The solution crosses into a different year.

Ways to calculate 42 years ago

  1. Calculate it: Start with a time ago calculator. 42 years is easiest solved on a calculator. For ours, we've already factored in the 18 days in July + 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 July's calendar: Begin by identifying 18 Jul on a calendar, note that it’s Monday, and the total days in June (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 42 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()-42 to get or =WORKDAY(TODAY()), -42, cell:cell) for working years.

Working years in 42 calendar years
