585 weeks ago from today was 13 Sep 2013, a Friday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 585 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 4095 days on a calendar until getting my solution of Friday September 13, 2013.

How we calculated 585 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 585 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 29 Nov, then set the calculation - 585 weeks, and factored in the year 2024
  2. Noted your current time of year: 585 weeks in November will bring us back to October or further.
  3. Counted backwards weeks from current day: date - 29 Nov, factoring in the 29 days left in November to calculate Friday September 13, 2013
  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 13

  • Current date: 29 Nov
  • Day of the week: Friday
  • New Date: Friday September 13, 2013
  • 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 585 weeks ago

  1. Calculate it: Start with a time ago calculator. 585 weeks is easiest solved on a calculator. For ours, we've already factored in the 29 days in November + 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 November's calendar: Begin by identifying 29 Nov on a calendar, note that it’s Friday, and the total days in October (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 585 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()-585 to get or =WORKDAY(TODAY()), -585, cell:cell) for working weeks.

Working weeks in 585 calendar weeks

585 weeks is Friday September 13, 2013 or could be if you only want workdays. This calculation takes 585 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 13, 2013 date.
