Solution

Friday September 18, 2020

225 weeks ago from today was 18 Sep 2020, a Friday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 225 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 1575 days on a calendar until getting my solution of Friday September 18, 2020.

How we calculated 225 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 225 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 10 Jan, then set the calculation - 225 weeks, and factored in the year 2025
  2. Noted your current time of year: 225 weeks in January will bring us back to or further.
  3. Counted backwards weeks from current day: date - 10 Jan, factoring in the 10 days left in January to calculate Friday September 18, 2020
  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 September 18

  • Current date: 10 Jan
  • Day of the week: Friday
  • New Date: Friday September 18, 2020
  • New Date Day of the week: Friday
  • Counting backward from September puts you back into the summer! September is the official start of fall.
  • 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 225 weeks ago

  1. Calculate it: Start with a time ago calculator. 225 weeks is easiest solved on a calculator. For ours, we've already factored in the 10 days in January + 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 January's calendar: Begin by identifying 10 Jan on a calendar, note that it’s Friday, and the total days in (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 225 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()-225 to get or =WORKDAY(TODAY()), -225, cell:cell) for working weeks.

Working weeks in 225 calendar weeks

225 weeks is Friday September 18, 2020 or could be if you only want workdays. This calculation takes 225 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 September 18, 2020 date.
