525 weeks ago from today was 19 Dec 2014, a Friday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 525 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 3675 days on a calendar until getting my solution of Friday December 19, 2014.

How we calculated 525 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 525 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 10 Jan, then set the calculation - 525 weeks, and factored in the year 2025
  2. Noted your current time of year: 525 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 December 19, 2014
  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 December 19

  • Current date: 10 Jan
  • Day of the week: Friday
  • New Date: Friday December 19, 2014
  • New Date Day of the week: Friday
  • December marks the end of the year, so account for all the out of office notifications when counting backwards.
  • 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 525 weeks ago

  1. Calculate it: Start with a time ago calculator. 525 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 525 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()-525 to get or =WORKDAY(TODAY()), -525, cell:cell) for working weeks.

Working weeks in 525 calendar weeks

525 weeks is Friday December 19, 2014 or could be if you only want workdays. This calculation takes 525 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 December 19, 2014 date.
