What was the date 78 weeks ago?

Solution

Friday October 20, 2023

Date Range: 78 weeks

78 weeks ago from today was 20 Oct 2023, a Friday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 78 weeks from now will bring us back to pre 2024 and we’ll need to factor this into our subtraction because it will change the calendar and fiscal years. For larger calculations like this, I start by subtracting total days, then counting backwards 546 days on a calendar until getting my solution of Friday October 20, 2023.

How we calculated 78 weeks 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 78 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 18 Apr, then set the calculation - 78 weeks, and factored in the year 2025
  2. Noted your current time of year: 78 weeks in April will bring us back to March or further.
  3. Counted backwards weeks from current day: date - 18 Apr, factoring in the 18 days left in April to calculate Friday October 20, 2023
  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 October 20

  • Current date: 18 Apr
  • Day of the week: Friday
  • New Date: Friday October 20, 2023
  • New Date Day of the week: Friday
  • October marks the start of Q4 so counting backward will put you back into the 3 fiscal quarter.
  • This calculation crosses at least one month. Remeber, this will change our day of the week.
  • 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 78 weeks ago

  1. Calculate it: Start with a time ago calculator. 78 weeks is easiest solved on a calculator. For ours, we've already factored in the 18 days in April + all number of days in each month and the number of days in . Simply add your weeks and choose the length of time, then click "calculate". This calculation does not factor in workdays or holidays (see below!).
  2. Use April's calendar: Begin by identifying 18 Apr on a calendar, note that it’s Friday, and the total days in March (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 78 times weeks by weeks, subtracting weeks from until your remainder of weeks is 0.
  3. Use excel: For more complex weeks calculations or if you h8 our site (kidding), I use Excel functions like =TODAY()-78 to get or =WORKDAY(TODAY()), -78, cell:cell) for working weeks.

Working weeks in 78 calendar weeks

78 weeks is Friday October 20, 2023 or could be if you only want workdays. This calculation takes 78 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Friday October 20, 2023 date.
