825 weeks ago from today was 28 Apr 2009, a Tuesday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 825 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 5775 days on a calendar until getting my solution of Tuesday April 28, 2009.

How we calculated 825 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 825 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 18 Feb, then set the calculation - 825 weeks, and factored in the year 2025
  2. Noted your current time of year: 825 weeks in February will bring us back to January or further.
  3. Counted backwards weeks from current day: date - 18 Feb, factoring in the 18 days left in February to calculate Tuesday April 28, 2009
  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 April 28

  • Current date: 18 Feb

Ways to calculate 825 weeks ago

  1. Calculate it: Start with a time ago calculator. 825 weeks is easiest solved on a calculator. For ours, we've already factored in the 18 days in February + 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 February's calendar: Begin by identifying 18 Feb on a calendar, note that it’s Tuesday, and the total days in January (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 825 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()-825 to get or =WORKDAY(TODAY()), -825, cell:cell) for working weeks.

825 weeks is Tuesday April 28, 2009 or could be if you only want workdays. This calculation takes 825 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Tuesday April 28, 2009 date.
