What was the date 491 weeks ago?

Solution

Sunday November 15, 2015

Date Range: 491 weeks

491 weeks ago from today was 15 Nov 2015, a Sunday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 491 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 3437 days on a calendar until getting my solution of Sunday November 15, 2015.

How we calculated 491 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 491 weeks ago gets calculated on each visit:

  1. We started with date inputs: used current day of 13 Apr, then set the calculation - 491 weeks, and factored in the year 2025
  2. Noted your current time of year: 491 weeks in April will bring us back to March or further.
  3. Counted backwards weeks from current day: date - 13 Apr, factoring in the 13 days left in April to calculate Sunday November 15, 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 November 15

  • Current date: 13 Apr
  • Day of the week: Sunday
  • New Date: Sunday November 15, 2015
  • New Date Day of the week: Sunday
  • In Novemeber, account for the end of the year holidays 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.

Ways to calculate 491 weeks ago

  1. Calculate it: Start with a time ago calculator. 491 weeks is easiest solved on a calculator. For ours, we've already factored in the 13 days in April + 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 April's calendar: Begin by identifying 13 Apr on a calendar, note that it’s Sunday, and the total days in March (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 491 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()-491 to get or =WORKDAY(TODAY()), -491, cell:cell) for working weeks.

Working weeks in 491 calendar weeks

491 weeks is Sunday November 15, 2015 or could be if you only want workdays. This calculation takes 491 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday November 15, 2015 date.
