Solution

Thursday October 29, 2015

480 weeks ago from today was 29 Oct 2015, a Thursday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 480 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 3360 days on a calendar until getting my solution of Thursday October 29, 2015.

How we calculated 480 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 480 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 09 Jan, then set the calculation - 480 weeks, and factored in the year 2025
  2. Noted your current time of year: 480 weeks in January will bring us back to or further.
  3. Counted backwards weeks from current day: date - 09 Jan, factoring in the 9 days left in January to calculate Thursday October 29, 2015
  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 October 29

  • Current date: 09 Jan
  • Day of the week: Thursday
  • New Date: Thursday October 29, 2015
  • New Date Day of the week: Thursday
  • October marks the start of Q4 so counting backward will put you back into the 3 fiscal quarter.
  • 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 480 weeks ago

  1. Calculate it: Start with a time ago calculator. 480 weeks is easiest solved on a calculator. For ours, we've already factored in the 9 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 09 Jan on a calendar, note that it’s Thursday, 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 480 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()-480 to get or =WORKDAY(TODAY()), -480, cell:cell) for working weeks.

Working weeks in 480 calendar weeks

480 weeks is Thursday October 29, 2015 or could be if you only want workdays. This calculation takes 480 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday October 29, 2015 date.
