81 weeks ago from today was 04 Jan 2023, a Wednesday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 81 weeks from now will bring us back to pre 2023 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 567 days on a calendar until getting my solution of Wednesday January 04, 2023.

How we calculated 81 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 81 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 24 Jul, then set the calculation - 81 weeks, and factored in the year 2024
  2. Noted your current time of year: 81 weeks in July will bring us back to June or further.
  3. Counted backwards weeks from current day: date - 24 Jul, factoring in the 24 days left in July to calculate Wednesday January 04, 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 January 04

  • Current date: 24 Jul
  • Day of the week: Wednesday
  • New Date: Wednesday January 04, 2023
  • New Date Day of the week: Wednesday
  • Counting back form January will put you close, if not passed, the previous year.
  • This calculation crosses at least one month. Remeber, this will change our day of the week.
  • The solution crosses into a different year.

Ways to calculate 81 weeks ago

  1. Calculate it: Start with a time ago calculator. 81 weeks is easiest solved on a calculator. For ours, we've already factored in the 24 days in July + 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 July's calendar: Begin by identifying 24 Jul on a calendar, note that it’s Wednesday, 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 81 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()-81 to get or =WORKDAY(TODAY()), -81, cell:cell) for working weeks.

Working weeks in 81 calendar weeks

81 weeks is Wednesday January 04, 2023 or could be if you only want workdays. This calculation takes 81 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Wednesday January 04, 2023 date.
